A star is an active entity. It is consuming hydrogen in nuclear reactions causing it to emit heat, light and other electromagnetic radiation. Depending on the star, when it uses up all its hydrogen during its active life it shrinks into a small thing called a white dwarf. It is white because it is glowing from the heat of the sun it once was, but it is no longer a star. The star it once was had died.
What else can I help you with?
When a star has no fuel left and it's outer layers escape into space it is what?
It is dead. It becomes a black dwarf, just a rock.
What is the core of a sun like star called when its dead?
A white dwarf
Are white dwarf stars young?
No. A white dwarf is a remnant of a dead star.
Why would a white dwarf become a red dwarf?
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
Why is a star to be dead when it becomes a white dwarf?
At that stage, it will no longer produce energy. All the energy it radiates out is its residual heat, and it will gradually get colder and colder. Due to its small size and high density, however, it will take trillions of years for the white dwarf to become a black dwarf.
Why is a star said to be dead when it becomes a white dwarf?
At that stage, it will no longer produce energy. All the energy it radiates out is its residual heat, and it will gradually get colder and colder. Due to its small size and high density, however, it will take trillions of years for the white dwarf to become a black dwarf.
What is is a cold dead star called?
A cold dead star is called a white dwarf. It is formed when a star has exhausted its nuclear fuel and collapsed under gravity, shrinking to a small, dense, and dim object.
What is the relationship between a giant and a white dwarf?
A red giant is old to middle aged star and a white dwarf is dead star so the relationship is they are both are dead and alive.
Why is a star said to be dead when it is a white dwarf?
after the star implodes an explodes it becomes a white dwarf or a black hole Because it has used up all of it's fuel and has nothing left to convert into energy (unless it can accrete additional fuel from a companion star).
What is the final stage in the suns cycle life?
White Dwarf then Black Dwarf=Dead Star
What do you think the difference is between a black dwarf and a supernova explosion?
A black dwarf is a dead white dwarf. By dead, I mean a star that no longer burns. A white dwarf, in turn, is a dead "moderate" star (a star like our sun). So a black dwarf is a star that's died twice, with mass not much higher or probably lower than that of our sun. A supernova, is the "death" of a star that's really huge. By huge, I mean it has a mass that's considerably higher than that of our sun. That kind of star doesn't turn into a white dwarf. Rather, it becomes either a neutron star (pulsar or non-pulsar) or a black hole.
What dwarf in Snow White says she's dead?
