A white dwarf cooking into a black dwarf
Black Dwarf's are theoretical. They are the end point of a White Dwarf star, after it has finished cooling down. The universe is not old enough for one to have completely cooled into a Black Dwarf. See related question.
A black dwarf is a theoretical end-stage of a white dwarf star in the far future, after it has cooled down and no longer emits light. White dwarfs are hot, dense remnants of low to medium mass stars at the end of their evolution.
Before a white dwarf, a star would undergo the red giant phase. After a white dwarf, a star may end its life cycle as a black dwarf, although no black dwarfs are currently known to exist in the universe due to the long timescales required for a white dwarf to cool down.
When a white dwarf star no longer emits energy, it becomes a black dwarf. Black dwarfs are theoretical end points of stellar evolution where all nuclear reactions have ceased, and the star has cooled down to the background temperature of the universe.
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.
Assuming you mean a "main sequence" yellow star, it's a white dwarf star. In the end that fades to a black dwarf.
