A black dwarf is a hypothetical stellar remnant, created when a white dwarf becomes sufficiently cool to no longer emit significant heat or light.
The crucial point is hypothetical, as the time required for a white dwarf to reach this state, is older than the Universe itself.
Estimates place the temperature to be around 0.06 to 5 kelvin.
What else can I help you with?
What remain of a star that has no fuel but glows faintly is a black dwarf?
A black dwarf is a theoretical stellar remnant that is predicted to form when a white dwarf cools down completely. It is essentially a cold, dark, and compact stellar remnant with no nuclear fusion activity. No black dwarfs are currently known to exist in the Universe due to the immense timescales required for white dwarfs to cool down to become black dwarfs.
How far is the earth to the black dwarf star?
There are not black dwarfs. It would take trillions of years for a white dwarf to cool to a black dwarf, which is more than the current age of the universe.
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.
Do star that has no fuel but glows faintly is a black dwarf?
No, it is a red dwarf
What is the next stage after The white dwarf stage?
the next stage of a white dwarf is the black dwarf which is form when the degenerate electron slowly cools down by thermal radiation but the time required for a white dwarf to become a black dwarf is bigger than the current age of universe so the evidence of a black dwarf isn't found yet
What is a cold star?
It is called a Black Dwarf

What does a black dwarf burn?
A black dwarf does not burn anything. A black dwarf is the cooled remnant of a dead star.
How long will it take for a brown dwarf to become a black dwarf?
A brown dwarf will never become a black dwarf. A black dwarf is what becomes of a white dwarf. This process takes hundreds of trillions of years.
When was The Black Dwarf created?
The Black Dwarf was created in 1817.
When did The Black Dwarf end?
The Black Dwarf ended in 1824.
When was Black Dwarf Hornbill created?
Black Dwarf Hornbill was created in 1861.
When was The Black Dwarf - personage - born?
The Black Dwarf - personage - was born in 1740.
When did The Black Dwarf - personage - die?
The Black Dwarf - personage - died in 1811.
When was Dwarf black stingray created?
Dwarf black stingray was created in 2008.
What will happen to the sun 12 billion years from now?
It will end its main sequence life and now begins to cool and dim, changing from a dense white dwarf into a cold, inactive black dwarf.
Is a dead star the some as a black dwarf?
No, a dead star is different from a black dwarf. A black dwarf is a type of stellar remnant, but not all stars become black dwarfs. When a star dies it will leave behind a white dwarf, a neutron star, or a black dwarf as a remnant depending on its mass. Given enough time a white dwarf will eventually cool to a black dwarf. The universe is not old enough for this cooling to have happened yet.
