MPL3D Solar System Rapid rotating stars

[5000mahmud]

why are they not a sphere?

[mpl3d]

@5000mahmud, they are not a sphere because the high spin speed.

They spin so fast that they get deformated to an ellipsoidal shape, with an enlarged equatorial radius.

[mpl3d]

*deformed

[5000mahmud]

@mpl3d ok but what will happen if you put a planet can you tell me plz

[mpl3d]

@5000mahmud, yes, a planet can exist orbiting these type of stars. They will have an ellipsoidal shaped sun in the sky. Interesting, isn't it?

[CHOPMOP10]

these are deadly dangerous stars no planets like earth could bare its violent behavior i like our sun( FOR NOW)

[mpl3d]

@CHOPMOP10, quite true, we are fortunate :)

[TheSwanprincess16]

good job

[mpl3d]

@TheSwanprincess16, hey thanks.

[FunkMan53]

The music cuts truly suck! Would have been better to let the 60's music just play from beginning to end.

[mpl3d]

Indeed, the original uploaded video was that way. And the uploaded version was fine. Later, some YouTube processing damaged the audio.

Original version is available at mpl3d gallery web page.

[nine9s]

When you give the radii, is that from pole to pole or across the equator?

The text goes by awfully fast. It's enough time to recognize the words, but not enough to absorb what they mean. For me anyway. :-)

[mpl3d]

Radii for stars is given in polar radius, that is, measured in the spin axis.

Sorry if the text goes fast. By the way, you might want to take a look to the MPL3D binary stars video. It shows a contact binary around minute 7:00 (similar to those 'peanut' stars ;o)

[rogerush]

That's what the pause button is for. Not meant to be insulting, but just a tip that there is a pause button, in case you were wondering what you could use it for.

According to New Science Space, "a dense stellar corpse called a neutron star has been found spinning at an astonishing 1122 rotations per second 1.5 times faster than any other star. If confirmed, the finding could bolster the possibility of exotic "soft" states of matter inside dense stars."

And if our sun were the size of a garden pea, some stars are the size of a football stadium - a few even bigger.

See: YouTube's "The Real Perspective on the Solar System - With Music, (to the right).

[mpl3d]

Interesting, indeed.

[UltraMarine117]

damn i didn't knew there were stars that actualy get bigger and smaller every few hours Pulsating Stars Hmm intresting

[solidsnake2112]

I would not want to be around that eruptive star..

[wally2078]

There are some few stars whith rotations periods about only 1000 Hz!!!!!!! (rotations per second). These stars are called neutron stars.

[tegan71969]

Is the variation in rotation time due to the mass of the object?

[mpl3d]

I don't really think so, although all factors matter. I guess it has more to do with the origin of the star and the way it was conformed.

[tegan71969]

I thought that at first, but figured physics would be involved in rotation speed. My first guess was during the evolution of the planet somehow the coming together of material created the speed of rotation. Do we know exactly what causes the amount of rotation of a planet? I'm interested to know.

[mpl3d]

I'd say that stars rotation starts with the initial rotation of the gas/dust cloud that they originated from. The initial spin of the cloud could be a result of magnetic, thermal and/or gravitational interaction of the particles. Over time, knots of material clump together and  when the system condenses it inherits the inertia of that original spin. Not really sure, as we haven't been here long enough to tell.

[tegan71969]

Has the forming of a star or planet been observed in recent times?

[mpl3d]

I don't think so. That's what I mean, it takes so long that it cannot be observed.

[CadenRolland]

Great but it was hard to visualize the huge sizes. 23 times the sun,would that reach earth? How big are these things compared to the solar system?

[mpl3d]

Nice question, well you can imagine a Sun in the sky 23 times larger.

That is already huge, specially for spin radial velocities, around 15 million kilometers in radius, but it won't even reach Mercury, that orbits at around 45 million kilometers from the Sun center, at its nearer point to it.

[emilypalmer2]

太短了吧 太短了吧 太短了太短了吧

[googollearning]

why does the sun take 25 days to rotate and most of the stars you featured less than a day. Is it your selection or just that the sun is slower...

[mpl3d]

The Sun is included as our known reference for comparison purposes, just that. Its spin rate is not specially slow, rather it helps to understand the extraordinary spin speeds of the real fast rotators.

[bbbl67]

I suspect that these are special odd-ball cases of stars that rotate unusually fast. The Sun may be much more representative of the majority of other stars.

[mpl3d]

True, although fast-spinners are not so rare.

[mpl3d]

Thanks all for your comments.

[lunaticprophet]

what's the name of the song??

[mpl3d]

Glad you like it, it is "Cruise" by Funkie Monkie. It is a premiere.

[bignewgame]

Nice job!

[RexNunc]

mi perro mucho gusta la musica :) muy bien

[darkblue64]

como vinimos a parar en este increible universo??

[ORACLE063]

Wow great video !! Thanks for posting!!

[eisabeth]

BEAUTIFUL!!!!!!

[mpl3d]

Thank you very much :o)

[babegurlxazian]

my toes are dancing with the music

[hopwas2007]

What can i say? Great video i was tranced by it! One of best video i ever seen

[mpl3d]

Great! Thank you very much :o)

If you want to get tranced again, perhaps you'll enjoy my 'Sun lava' video.

[trongs01]

I guess u r rite, i am not too keen with such specific details on every star

[mpl3d]

No problem, I just commented it as an anecdote, and to share what I know so far. Always thankful for your interest.

[trongs01]

I hear Deneb can be interesting since its rotational velocity is very high, giving it an egg shape

[mpl3d]

Alpha Cygni? Yes, it is quite interesting because of its size and brightness, but according to my data, it does not really rotate very fast, sorry. As far as I know, it has a estimated rotational velocity around ten times that of our Sun, but since it is also 200 times bigger, it may need more than a year to complete one single revolution/turn.

[tornado1siren1geek]

Why can't we have a blue sun?

[mpl3d]

That would be spectacular, of course.

[Buzzlybonk]

A Pink sun would be fine with me.

[bbbl67]

How would we see it against the blue sky then? ;)

Seriously though, blue stars are usually much hotter and short-lived compared to the Sun. I suspect if we lived near a blue star, we wouldn't have enough time to have evolved to the point where we'd wonder why it was blue, before it blew up on us.

[WonderRaZ]

all your videos are awesome, thx!

[mpl3d]

Thanks a lot :o)

[10up]

if you had a comparison of the sun and that last big star, this video would have been so much cooler!

[mpl3d]

Well, thanks for the advice :o)

I tried to maintain some order, so that's why it goes from smaller/slower stars (Sun) to the bigger/faster (Tsih). This way it goes in crescendo and the last star is the more impressive of them all. Therefore I recommend to watch it until the end!

[EmmyKokoro]

Cooler? Two Suns? :p
