Wow It Helps Me In My Lesson in Science

Hi Kassie and Zac

mhs \m/

OMG dunraven school? i go there

[FluffyBunniesOnFire]

I hear the sun is 2nd generation, but I also hear it is 3rd generation.

[DigitalAffliction]

Michio Kaku could explained this in much funnier way ... He uses some words just as he is telling a fairytale to a toddlers XD hahaha ... anyway thanx for the vid i needed for my next exam at school :)

[onefortears19]

thank you really much for this, it will be really helpful in my Physics project

[dappledopple]

THANKS! this video has made things alot clearer for me. than some of the other videos the table at the end finalized it clearly

thanks

@dappledopple

No problem - glad it helped! Thanks for commenting.

[fell07]

im not one of your physics students

[applecakepie]

i lold at the sun will eat her children XD

[DizzyDancingStar]

This video has helped A LOT!! Thankyou very very much! Great summary of the life of the star, but I'm confused as to what Stellar is?

[DunravenScience]

A pleasure! "Stellar" is another word for "star" and is often used when describing properties of stars e.g. "stellar constellation" instead of "a constellation of stars."

[magicn3ss]

great video, the only correction id have to make is there is one other more powerful star explotion....a hypernova, but those are quite rare :)

[DunravenScience]

You are correct - I will have to do a new version which mention hypernovae and hypergiants. Thanks for the comment!

@DunravenScience

good job on this fascinating information. l love stars and the universe.

[lollipopbrigade]

if the star is 10x the mass of the sun it turns into a Black hole, 4x or more it turns into a neautron star.

Thanks for the video, really helpful!

[amitnarayankar]

this was the best explanation of the star life cycle.........esp the last summarized table.........thanks.

[DunravenScience]

Glad you liked it :-)

Please let other people know about it.

[phatbeauty08]

ok ty

[phatbeauty08]

thats not it...T.T can you tell me what the name of the song is or where you got it...its soothing ^^

[Dramactica]

@phatbeauty08

Sam Sparro--- Black and Gold. good song. 

[phatbeauty08]

lol nvm i guess i should have clicked on the ads be4 askin thanks....i watched this in science lol

[phatbeauty08]

i like the music...do u know the name of it

[BigGreedyBastard]

Anyone know the min number of solar masses it takes for super-nova that form a black hole?

One more question: Does the main sequence just refer to fussion of hydrogen to helium and does the fussion of all after helium mean the star is no longer in the main sequence?

TIA

[DunravenScience]

Thanks for your comment!

I believe its about 20 solar masses - but after the supernova event the core remnant must be 4 solar masses or heavier.

Helium to (say) lithium fusion requires higher core pressures and temperatures - the star can only achieve this by shrinking its core which results in an expansion of its outer layers i.e. it enters the red giant phase. So, yes, any fusion after helium means the star has left the main sequence.

pretty cool
