The Universe - newspaper - was created in 1860.
The Black Dwarf was created in 1817.
Black Dwarf Hornbill was created in 1861.
Dwarf black stingray was created in 2008.
Black-headed Dwarf Chamaeleon was created in 1865.
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 ended in 1824.
A star of similar mass to the sun dies and collapses, forming a white dwarf which cools, forming a black dwarf.A mass of dust and gas too small to ignite fusion collapses, forming a brown dwarf which cools, forming a black dwarf.
Current thinking on stellar evolution is that once a white dwarf cools off to a black dwarf stellar remnant, it would be generally stable but inert. It would need to acquire more mass to collapse to a neutron star or black hole for example.
The Black Dwarf - personage - was born in 1740.
The Black Dwarf - personage - died in 1811.
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.
