Does a white dwarf last forever?

Answer 1

What happens to stars when they die depends on how massive they are. For instance stars the size of the Sun turn into white dwarfs that eventual cool, Stars about 8*thr size of the Sun explode to form Neutron Stars (Pulsars) and very very big stars explode and leave behind a black hole.

Answer 2

Stars do NOT "die" per se. They use up all of their fuel and eventually burn out in one way or another! Nothing ever "Dies" it is just re-purposed by the Universe (God), whatever suits your need.

Answer 3

The fate of a star is determined by the mass of the star. Very large stars will destroy themselves in a supernova, blowing off the outer layers of the star and crushing the core into a black hole.

Stars bigger than about 3 times bigger than our Sun will collapse into a neutron star. Stars like our Sun will eventually expand into a red giant, and then shrink down to a white dwarf star.

Answer 4

That depends on how massive the star is. For ordinary stars like our Sun, or smaller dwarf stars, they don't really "die"; they just shrink into white dwarf or brown dwarf stars. In a few hundred billion years, they may become "black dwarf" stars, but the universe isn't old enough for that to have happened yet.

Large stars burn out more quickly, and die more spectacularly. Fairly massive stars will go nova, and leave behind a "neutron star", while very large stars may go "supernova" and become black holes.

Answer 5

"White dwarf stars do not become supernovas. White dwarf stars are what happens when a normal Sun-sized star has reached the end of its life."

This answer is partially correct. A white dwarf is the final stage of a main sequence star such as the sun. However, a white dwarf can become supernova. A White Dwarf Star may accumulate accrete (material from a companion star) until it reaches critical mass and undergoes a thermnuclear explosion (AKA supernova).

Answer 6

you must understand that understanding the way the stars die, you need to know things about the star's life. In the related links below I posted a good article by NASA.

Ahhh.... you mean stars in space. In larger stars, fusion continues until the iron core has grown so large that it can no longer support its own mass. This core will suddenly collapse as its electrons are driven into its protons, forming neutrons and neutrinos in a burst of inverse beta decay, or electron capture. The shockwave formed by this sudden collapse causes the rest of the star to explode in a supernova. Supernovae are so bright that they may briefly outshine the star's entire home galaxy. Most of the matter in the star is blown away by the supernovae explosion and what remains will be a neutron star (which sometimes manifests itself as a pulsar or X-ray burster) or, in the case of the largest stars (large enough to leave a stellar remnant greater than roughly 4 solar masses), a black hole. In a neutron star the matter is in a state known as neutron-degenerate matter, with a more exotic form of degenerate matter, QCD matter, possibly present in the core. Within a black hole the matter is in a state that is not currently understood.

Answer 7

It will cool down and become a cold black dwarf

Answer 8

Neutron star, Black hole, or White Dwarf star.

Answer 9

No, a white dwarf does not last forever. A white dwarf will eventually cool to become a black dwarf.

Answer 10

a black hole, white dwarf, neutron star
