White dwarf star explosion into a Ia type supernova

[caffiend81]

I'm a bit confused by the dislikes. People dislike reality? How sad.

[bobjackson7]

mushrooms

[PyroXLord]

Popcorn

[YIMY6]

One please

[xXInsaneLlamaXx]

Popcorn anyone?

[zepeake]

I thought a dwarf star was a star that already exploded does it do it again???That's why its dwarf I mean really if a reall star explode it would either turn into a black whole or a dwarf star and live on forever or some other thrid thing might happend

[balios1]

@zepeake

An average sized star like our sun will eventually turn into a red giant and then when it completely runs out of fuel, into a white dwarf star. There will be no explosion during that process. However, if you dump a whole bunch of hydrogen onto that white dwarf star (from a companion star), it will explode like in the video.

Very large stars (the ones that explode by themselves) don't turn into dwarf stars. They supernova and turn into a neutron star or a black hole.

[zepeake]

@balios1 K that's cool

more like a mushroom sprouting :P

[Aderpherp]

mmmmmmmm popcorn

[geertownzzz]

ice cream!#

[MeAmAPeople]

IT'S A SPLOSION !!!

[T0B0KKE]

Giant thermonuclear bomb mushroom cloud...

[Toxiclevideos]

This happens when a star burns out all its hydrogen and helium, causing its core to collapse and in a split second, the star explodes, in the term, "Supernova".

[cybercheeseburger]

@Toxiclevideos actually that's a type 2 supernova, in this case, it's a white dwarf that has gained enough material from its companion star to begin fusion.

[Helge129]

@Toxiclevideos This is about a Type 1A supernova, not a Type 2 supernova.

[Arxtile]

looks more like a defected popcorn super nova

[TheCaptainLulz]

Do all of these type of explosions begin in the heart of the star or can they begin in other locations within the star

[kival71]

@TheCaptainLulz

The heart of the star collapses on itself. Its the exterior of the star, the outer shell that explodes into space.

[Andreware]

So is the blue thing the white dwarf? I thought supernova occured when mass accumulated on its surface, and THAT reacted.

[wengneuda13]

yellow giant brain not giant brain

[wengneuda13]

It looks like giant popcorn and giant brain 

[50secondsaway]

Looks like a sad mushroom. :c

[anand308]

I thought only a neutron star can burst into a supernova because of the pauli exclusion principle applied to neutrons, which causes the rebound of the core of the star... so that means your video description doesnt make sense...

[TnJFilms1]

lol 0:57 looks like an asian guys buthole if you pause it.

[edstudios]

@TnJFilms1

It actually looked like your mom's viral infected vagina!

[bilirubinu]

you`re all so smart and funny... omg rofl, ignorant a#$holes!

@glitchman161 yea chuck norris is all gas, hahaha

[yorgan007]

looks like a giant piece of popcorn

[KissMyFeetButtMunch]

What makes the explosion go back around itself? Because I thought in an explosion it would blow out into space, but here the explosion clouds back. D: Times like these I wish I took science.

[jemmani22]

@KissMyFeetButtMunch not sure but probably some sort of gravitational thing. or something that has to do with the star

[UberCookieboy]

So white dwarves are basically ticking time bombs?

[haggis357]

lol popcorn.

[Glennfalconi]

@haggis357 * Slaps on own forhead *

[puncheex]

Something I found out about this: The sim ends before the action is over. The emerging eruption on one side causes surface shock waves that all merge at the antipode of the emergence, and from there a total fusion wave walks through the star's body fusing everything inside in one stupendous explosion. The entire action, from the start near the center to the completion of the final fusion wave through the star, takes no more than 5 seconds.

[Kai262958]

it would be nice to do this with a super highspeed computer and have a particle based explosion and a nice physics engine but use billions upon billions of particles for the explosion.

[dinoman1997]

looks like popcorn

[TheReasonWhyGuy]

This is WAY beyond my area of "expertise", and I make it my business to make as many things fit into my "area of "expertise"" ;)

[shoshanish]

omg

mario had to many shrooms

or

omg,

mario better not eat that mushroom.

[Interleap]

@MichaelDoakTV i always wondered do you think their might be planets that are alive out there?

Like a planet that has turned into a huge brain by coincidence.

[MichaelDoakTV]

@Interleap maybe ya never know

[jemmani22]

@Interleap our universe is so big its rediculus. anything could happen out there.

[endlesswick]

Our planet and in fact our bodies are made up of material formed in the fusion process of stars, released and further formed by super nova. Don't take life for granted, alot had to occur for it to happen.

[DJDeegeee]

This shit is boring.

[PersonFromNorway]

:O BOOM!

[buddy39914]

looks like a jellyfish

[endlesswick]

Does a Type Ia supernova completely destroy the white dwarf star? Anyone know?

[WeAreTheRobots]

@endlesswick

Probably not, the star is very likely to be completely destroyed. Technically, one says that "there is no gravitationally bounded remnant", meaning that no remnant compact object like a neutron star or a black hole is left, as it does occur with supernovae type II, for example.

Thus, in type Ia, the star is disrupted and its mass just thrown away.

[EndeChayer3]

It does not

[endlesswick]

I have done some research on this subject, and it does appear that the white dwarf is completely destroyed in the type 1a super nova. The companion star is ejected from the star system, since the supernova stars gravity well no longer remains. The material that makes up the white dwarf is spread out into a nebula. New heavier elements are also formed from the energy of the supernova. This is one way how planetary building materials are formed, it is how we got here.

[puncheex]

@endlesswick: No. This is a Type 1a Supernova. The white dwarf is orbiting a red giant, and is pulling hydrogen off the giant which is landing on the dwarf's surface. Eventually, at a very specific size, the temperature is high enough to cause this surface material to go thermonuclear and explode like a huge h-bomb. It leaves the dwarf and the giant more or less unscathed (except the coating on the dwarf is of course gone), and they are free to start and do it all over again.

[endlesswick]

@puncheex: I am an amateur astronomer only, but I think you are referring to the smaller explosions that occur as the white dwarf accretes hydrogen from a companion star, the hydrogen fuses and makes a pretty good blast, called a nova. The mass of the star continues to increase, and eventually the heat and pressure are so great the the carbon in the center of the white dwarf fuses, and this makes a BIG explosion that compleatly destroys the star, this is refered to as a type 1a supernova.

[puncheex]

@endlesswick: Yeah, you're right, but I was sort of hoping some smart guy wouldn't come along and send me up. Ah, well.... :)

You're right, I was confusing the two. The Type 1a supernova completely envelopes and fuses all the material in the star, right up into the superheavy elements that decay in milliseconds, blasting them outwards just like a Type 2 supernova does. The only difference is that the debris is free of hydrogen, having fused it all.

Thanks for the correction, endlesswick.

[TnJFilms1]

lol 0:50 looks like a face if you pause it.

[MasterOfArm]

yeah.. lol

[SROThePlague]

@TnJFilms1 yes i realized that in the first time :D

[SpenceanatorTheNinja]

@TnJFilms1 looks like an lion face or somethin

[wengneuda13]

oh your right!

[ElChubbaChubba]

@TnJFilms1 its clealy a sign that jesus is coming.

[PSVCR7PSV]

@TnJFilms1 Simba of the lion king (without ears :p)

[manikase27]

Well if you both explode. however, it mains such a cloud strikes.

[Smorphine]

It's thinking-burning brain!

[Cervanteskid]

Lol at first i saw a mushroom and then it started looking like genital warts taking over your left nut XD

[TheSOAD8830]

it looks like ice cream! LOL!!!

[MrManisgreat]

i have no idea what any of you are talking about! but what is the blue circle supposed to represent?

[Nuker1337]

It's the surface of the white dwarf star.

[sam93d]

Pause at 00:50, looks like the aliens from the new War of the worlds :/

[rap1393]

holy shit

its like a giant mushroom

[Mafkaas120]

God???!!! Really fuck me man.

[dodoslovensko]

u must have strong pc to do this animation?

[hackerspiff]

It's not an animation exactly, it's a simulation. This kind of sim is usually done on some of the biggest supercomputers in the world (like at Livermore or Sandia Labs where they simulate nuclear tests).

This simulation is trying to show that when a white dwarf begins to go supernova, the collapse often progresses asymmetrically throughout the star, resulting in explosions that vary in brightness.

They used to pretend that these all had the same brightness but now know they vary a bit.

[hackerspiff]

Why does this matter? Type 1A supernovas (exploding white dwarfs) are used to measure distances to galaxies. According to the physics we understand, white dwarfs all explode when they hit about 1.44 solar masses. This implies that all white dwarfs put out the same amount of light when they explode. This makes them useful to measure distances to remote galaxies. The study of these lead to the stunning finding that the universe is accelerating in its rate of expansion...

[hackerspiff]

That finding has shaken the very foundations of astronomy. It takes a vast force or energy to make the universe increase its rate of expansion... a LOT of it. Where is this energy coming from?

Nobody knows.

[Zantheon]

is it at a constant rate of expansion? or does it vary? and wouldn't the energy be coming FROM these supernova that expand?

[hackerspiff]

The universe is expanding everywhere. Space appears where there was none. The rate was assumed to be constant and smooth everywhere, a fundamental property of the universe described by the "Hubble Constant"... (look that up on Wikipedia). The supernovae are merely a way to measure distances precisely and do not affect the expansion of space. But since they started measuring, they noticed that the expansion rate was slower for things that are much farther away.

[hackerspiff]

When we observe things far away from us, we see back in time (the light signal took time to get to us, so if we look at a galaxy that appears to be 1 billion light years away, we are seeing back in time 1 billion years). The older things seem to be receding from us slower than they should be, implying that the expansion of space was slower than it is now.

I don't remember the equation, but everyone talks about Einstein's constant for acceleration, implying steady acceleration.

[hackerspiff]

An accelerating rate of expansion is counter-intuitive... When you throw a ball in the air, it comes back down. If anything, the total gravity of mass in the universe should be causing things to slow down. Hence, sometimes physicists call the phenomenon causing the accelerating expansion rate "anti-gravity"... as if there is a force in the universe pushing everything apart, resulting in a net acceleration.

[Nuker1337]

It's called buoyant acceleration. The plasma mushroom cloud has a lower density than the rest of the star (which has about 300000x the density of water, so it rises very quickly). This means that in optimum conditions, there will be an acceleration upwards, the same as the acceleration toward the center of the star, if the rigidity of the star is 0 and the density of the mushroom is 0.

Adobe After Effects rocks!

Lol its look like the wierd thing (more mystrious than wierd) that on my foot!

[pepsiman456]

[12334567890qwertyuio]

in the begining it looks like a giant shroom

[coraxdjay]

looks like a fart of GOD

[jamm210]

haha

[dawg1157]

or from your mom

[coraxdjay]

its from your big fat ass you fattman

[dawg1157]

.... not as funny

considering im not fat

now ur mom on the other hand..... goddamn ...u need to take a train and two busses just to get on the bitches good side

[littshepkid]

Jesus?

[RAFL94]

no something more powerful than both jesus and god. You're not ready for such knowledge yet since you still believe in them. Some like me have moved on in our development. Just like it is religion. Were creating our own one and moving on because we have stopped believing in god. That's because we are smarter and understands the world much better. That's why you still believe in god and are not ready to move on to the next level. But please try. We need to develop naturally!!!

[startjumper]

u're like 15 years and shitting about god and like u know something about the world. Mayby u are the one who has to keep on trying to develop.

[RAFL94]

I'm not the only one. There are people from 10-110 years old that thinks the same as I do. I'm not bragging solo of how smart I am. I'm just one of very many involved of this kind of knowledge.

[startjumper]

yeah but u only know that god isnt real like i do :p but ur saying that u understand the world better than others , so what do u understand better than the ones who believe in god :D

[RAFL94]

I know god is real. But he isn't an old man who has emotions. He is energy. That's what I understand. Here's my top 4 list of the most powerful things. 1.Existence 2.Energy 3.Life 4.Emotions. Without existance there is no energy. Without energy there can't be life. Without life there can't be emotions. You're right that god created life. But not in the way you think. That's what I mean that I understand better. You think he by porpuse created life. But he didn't. It's a coincidence.

[startjumper]

so first u say u don't believe in god and now u say u do.

And what ur telling about ur theory i think , i know there is more than that to create life. First go to school and learn.

[RAFL94]

when I was 6 and begun school. I was smarter and understood better than my teachers. We could say that in grades from my age up to I began school. I've already learned what the 6th grade can. When I quit 6th grade I could everything you need to learn in school. Then 7th and 8th grade I've learned even more than you need too. So i've learned already, have you?

[lyue1996]

What Is A LA SuperNova?

[sammytav]

Thats cute.

[wazapman333]

Bible bash somewhere else plz.

[wazapman333]

U cant think that its either god or this.... whats it gonna be?

[Psycho0Robot]

What if god did this? He's omnipotent so he can do anything, right?

[Jsimp0487]

He could and I wouldn't be surprised.

Yet all of the what ifs come down to this.

People will reject God or the idea of God SO THAT, they can remain unaccountable to a higher authority.

That's all it comes down. Man is prideful and does not want to submit himself to an omnipotent and omnicient authority.

[runeraper98]

look like a spoon

lolz

[jmm1233]

looks like a skull near the end ,

[Delicatoboll]

This is actually an animation of a fart.

[raydavid100]

@Delicatoboll no it isn' t!

[SROThePlague]

@Delicatoboll u r right xD fart xD

[cdlsd]

my universe book says that planetary nebulas ONLY turn into white dwarfs

[ZineX07]

ehm planetary nebulas do NOT turn into white dwarfs! the sun does! and when doing so, it pushes of its outer hull and most of its original mass which then becomes the planetary nebula...

either you didnt read quite correct or your book is a piece of junk!

[shockboy0421]

theres a huge difference in hight quality lol
