what happens after a star dies??????

Answer 1

they form a blackhole ,, ,, yes ,,, a ,, blackhole!!!!!!

Answer 2

It can become one of several things: a neutron star, a white dwarf, or a black hole. These would all be considered "dead" stars, because none of them fuses elements like a star does.

A neutron star is an incredibly dense structure, essentially packed with neutrons into a phase of matter that is only possible under incredible pressures. There are no atoms at the interior, just neutrons. A pulsar is a well-known type of neutron star; it emits measureable electromagnetic pulses. Neutron stars rotate very rapidly due to conservation of angular momentum; it has the same momentum as the parent star when it spun at a slower pace, but a much smaller moment of inertia, requiring the acceleration. Neutron stars form from stars slightly heavier than the Sun.

A white dwarf forms from lighter stars, in a range that includes the Sun. When such a star runs out of hydrogen to fuse, it becomes a red giant and fuses heavier elements, until it cannot get enough energy to fuse anything else. It explodes in a supernova, creating a nebula and a white dwarf. The white dwarf consists mainly of oxygen and carbon and is extremely hot (and thus gives off light), but it is not creating any more heat like a star does. It eventually cools to form what is called a black dwarf (because it would not give off any light), but this takes hundreds of billions of years, longer than the age of the universe, so no black dwarfs exist.

Black holes form from heavier stars. A black hole is an object so dense that it has an escape velocity greater than the speed of light, a physical impossibility. Thus, no object within the "event horizon" of a black hole would ever be able to escape it. It requires a heavier star to form a black hole because it requires great gravitational forces to overcome something called "electron degeneracy pressure," which is what keeps a white dwarf from collapsing.

Answer 3

The size determines what happens to it. There are a few possibilites.
1.Neutron Stars- After a very large goes super nova it blows off it outer layers, revealing the core of the sun. Its gravity is so strong that it forces the neutrons on the atom to compress and the penetrates the nucleus. Turning it in to nothing but neutrons and other really small particles such as quarks. It is extremely dense and a teaspoon would weigh as much as 1,000,000 tons or if you droped a small marshmellow on it, it would have the power a(n) Hydrogen Bomb (the atom bomb).

1.Black Holes-I don't remember much about black holes but I remember some. Black holes, in fact predicts that they will be formed in nature whenever a sufficient amount of mass gets packed in a given region of space, through a process called gravitational collapse. As the mass inside the given region of space increases, its gravity becomes stronger and increasingly deforms the space around it, until ultimately nothing (not even light) can escape the gravity. At this point an event horizon is formed, and matter and energy must inevitably collapse to a density beyond the limits of known physics. Pulsars and Neutron Stars have been found inside black holes. Black will also suck in other stars. What ever passes the Event Horizen never comes back. Just like what happens in vegas stays in Vegas, What goes in a Black Holes never come out.

Pulsars- Are the same thing as Neutron Stars but its jets of uneeded material fly out to the east and west unstead or North and South.

White Dwarfs/Dead Star(s)- Happens after a star the size of the sun blows off it's outer layers. It will shrink in size untill it's roughly the size of earth. But it is no longer giving off heat. It will then fade into a dead star. It looks like a nebulea (thats what it is).

Answer 4

It depends upon what kind of star it started as. A star like our Sun will turn into a red giant, then end up as a white dwarf. Stars a little more massive at their "birth" will end up as a neutron star. And, the most massive stars will end up resulting in a black hole. Some will go nova or supernova along the way to their ultimate fates, again depending upon the initial mass at "birth".

Answer 5

The core finally cools into a white dwarf, then a black dwarf. This is what happens when a normal-sized star dies. If a really huge star dies, it has so much mass that after the helium is used up, it still has enough carbon to fuse it into heavy elements like iron. When the core turns to iron, it no longer burns.

Answer 6

A star is a big mass of hot gases that has enough mass to achieve stellar ignition. A star usually at it's birth has 90 percent hydrogen, 10 percent helium, it can't have more than 1 percent of heavier elements. It burns through a process called nuclear fusion where lighter elements with a smaller amount of protons such has hydrogen fuse together to. If two hydrogen atoms fuse together, they each have one proton, they fuse and now, their is two protons which means, it has turned into helium, two helium atoms can fuse and turn to heavier elements. After all gases are turned to elements like iron, the star will reach the end of it's life cycle and grow ten times bigger than it's original size. If it was a big star, it is now classed has a red super giant, if it was a small star, it is now classed has a red giant. From here on, if it is huge, it can explode into a hyper nova and turn into a black hole or neutron star. When a smaller star dies, it explodes in a supernova. It will be turned into a dwarf star and it's last light will die out after words. After it ignites, it's life span depends on how big it is, if it is a huge star, it will fuse it's gas source faster into heavier elements and die out quicker, if it is smaller, even though it will have less gases, it will burn them slower and live longer. Through it's life, it goes through a number of colors based on how long it has left to live.

Blue Youngest 50,000-25,000 degrees Celsius
Blueish White 24,999-10,000 degrees Celsius
White 9,999-7,500 degrees Celsius
Yellow 7,499-5,000 degrees Celsius
Orange 4,999-3,500 degrees Celsius
Red 3,499-2,500 degrees Celsius

IT IS MORE THAN YOU NEED TO KNOW BUT IT IS EVERYTHING YOU NEED TO EVER KNOW

Answer 7

matter being indestructible and stars being made of mater . they are never destroyed but are only changed from one to another .Change is the order of the universe /nature .everything continues to change and that is he sign of life .All Animate ,ate things Are compounds of inanimate things only.
the star dies when it's fuel is exhausted , meaning changed in to something that can not burn anymore and give out light . the dying star , Like a dying flame . will just expand before it collapses on to itself and In this process , it is said to pull everything around it to itself and become many times more in size leading to and infinite gravity of such proportions that even light does not escape the forces of gravity.in the absence of light emanating form the star , it would not be visible and it is called a black hole with in which a nuclear fission would e going on to explode one day giving rise to new stars , and galactic matters.

Answer 8

Well, if the star is big enough, say a Red Dwarf Star, then after it uses up all its gas it'll implode (collapse in on itself) because its centre of gravity is so strong. This creates a tiny, really dense point of gravity, so strong that it will suck in other stars, and effectively devour them. There are millions of black holes out there. Fortunately Earth is not on line to hit one :)

Answer 9

If it is a star like our sun, it will become a white dwarf. If it is a giant star that went supernova, it could either become a pulsar or a black hole.

Answer 10

I did a paper on this once. Hope my memory is right.
Some turn into red giants, expand real big, then blow themselves to smithereens. Some turn to white dwarves, where they shrink down right tight and burn small and bright. Really big ones can turn into black holes, when they collapse so much they suck it down big time.

Uh, I hope you weren't talking about pop culture....:)

Answer 11

A star will become either a black dwarf, neutron star, or black hole, depending on how massive it was.
