what happens when a star dies?

Question

i understand that when a star dies, it sucks in the planets. after that does it leave the galaxy? is the galaxy powerful enough to keep the dead star in its area so that a new one can be born? (educated researchers and whizzes only)

It depends.

Red dwarfs, the smallest of stars, give off almost no light. Because of the little energy they use, they can last trillions of years before just burning out.

Yellow dwarfs, like our sun, are different. Like many people think, they are the ones that last billions of years before undergoing a transformation to a red giant.

Blue giants and red supergiants last the shortest. Blue stars give off insane heat and are some of the most marvelous and brightest stars. The cost? They burn energy so fast, they only live for millions of years.

Either way, their fuel supply of hydrogen burns out, and have to resort to helium, expanding and cooling. When that rns out, if the star was a red dwarf, it doesnt even expand; it cools down and fades.

If it was a yellow dwarf, it became a red giant and srunk, red giant again, planetary nebua, then became a white dwarf. It will eventually become a black dwarf.

A super massive star runs completely out of gas. It cant contrast, so it exploides and creates either a black hole or a neutron star in its place

Answer 2

If the star is a big bigger than our sun to smaller, it becomes a 'red giant' for a few million years. Then it loses it's atmosphere and only the center of the star remains, without fuel, as a 'white dwarf'. Because it has no fuel it slowly cools and eventually stops glowing becoming a black dwarf.

If the star is much bigger than the sun, it also becomes a giant star. But later instead of losing it's atmosphere, the star becomes so hot and big that the pressure makes it 'collapse' on itself (like a soufle that rises too much then falls on it's own weight)... when this happens all that 'stuff' the star is made of contracts so much that it eventually explodes in a 'supernova'.

After that, a 'neutron' star remains, which is like a white dwarf but much smaller and far heavier. If the star is so big, the center can contract even further into a 'black hole', which has so much weight and gravity in a tiny space that even light can't escape it.

If the star is much smaller than the sun, they just slowly glow dimmer and dimmer until they die.

That's the simplest explanation!

Answer 3

A good example of what's left of a star that died are some nebula that you can see right in your backyard thru a telescope. Locate and look at M27 (dumbell nebula) and M57 (Ring nebula), there are many others like these that shed their outer shell when they die. The Orion Nebula is where stars are being born.

Answer 4

that depends on what kind of star it is. if it is a supergiant than i will explode in a blast called a supernova. after the explosion the matterials will colapse into itself at a very high rate creating a black hole. if it doesnt colapse quickly it may turn into a planitary nebula which has the capabilities of creating a new solar system or colapsing eventually into a new star.

Answer 5

Well, that depends on the star. It would most likely collapse. Creating a blackhole. An incredible amount of energy is released at that time.

Answer 6

I think it depends on the size of the star, big stars can change into black holes. For lots of facts and details check this out :

Answer 7

like all good stars, it goes to star heaven. Trust me I am a Catholic Republican, so I know what I am talking about, oh and researchers lie.

Answer 8

Usually there is a big obituary in the newspaper and a new conspiracy is born.

Answer 9

I think most of the time it is Boommmmmm! lol

Answer 10

high mass-supernova-black dwarf
very high mass-supernova-black hole
low mass-brown dwarf
