The same size as the white dwarf it was.

A black dwarf does not burn anything. A black dwarf is the cooled remnant of a dead star.
Black Dwarf Hornbill was created in 1861.
As a white dwarf loses energy and cools down, it eventually transitions into a black dwarf. A black dwarf is a hypothetical stellar remnant that has cooled to the point where it no longer emits heat or light. It is smaller and denser than a white dwarf.
A star that has burned out and no longer has fuel to sustain nuclear fusion in its core is called a white dwarf, not a black dwarf. A white dwarf is the remnant core of a low to medium mass star after its outer layers have been ejected. Over time, a white dwarf will cool down and eventually become a black dwarf, but this process takes billions of years.
No. Fusion has long since ceased by the time a stellar remnant becomes a black dwarf.
No, a black dwarf is not made of gases. A black dwarf would not be in state called electron degenerate matter.
A black dwarf does not burn anything. A black dwarf is the cooled remnant of a dead star.
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.
The Black Dwarf was created in 1817.
The Black Dwarf ended in 1824.

The Black Dwarf - personage - was born in 1740.
The Black Dwarf - personage - died in 1811.
Dwarf black stingray was created in 2008.
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.
A black dwarf.
Black-headed Dwarf Chamaeleon was created in 1865.
