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 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.
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.
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 happens to the core of a star after a planetary nebula occurs?
After a planetary nebula occurs, the core of the star collapses and becomes a white dwarf. This white dwarf slowly cools down over billions of years until it eventually becomes a cold, dark remnant known as a black dwarf.
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.
What kind of star forms when a white dwarf uses up all its energy?
A white dwarf is the remains of a dead star, not the birth of a new one.
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 small dead star?
A small dead star is typically a white dwarf, which is the leftover core of a star that was not massive enough to become a supernova. White dwarfs are very dense, about the size of Earth but with the mass of a star.
How a star becames a white dwarf?
A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
What is the final stage in the suns cycle life?
White Dwarf then Black Dwarf=Dead Star
What is the core of a sun like star called when its dead?
A white dwarf
