No. Fusion has long since ceased by the time a stellar remnant becomes a black dwarf.

Does fusion occur in white dwarf stars?
No. A white dwarf is the remnant of a star in which fusion as stopped.
What causes stars to change during the white and black dwarf phases?
A white dwarf no longer produces energy through fusion but remains hot from the residual heat of the star it once was. It will radiate that energy away and slowly cool as a result, eventually becoming 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.
Is a white dwarf capable of fusing elements?
Not normally. A white dwarf is the remnant of a star in which fusion has stopped. If, however, a white dwarf has a close binary companion star it can accrete gas from that companion. If enough gas collects on the white dwarf it can ignite a complex reaction change between the hydrogen gas and the carbon, nitrogen, and oxygen of the surface. Unlike the steady fusion in a main sequence star, the fusion on a white dwarf is a runaway reaction that results in a massive explosion called a nova, which drives away the accreted gas and ends fusion. If the white dwarf is massive enough the accretion of gas can trigger carbon fusion inside the white dwarf, resulting in an even larger explosion called a type Ia supernova, which destroys the white dwarf.
Does a star that has no fuel but glows faintly is a black dwarf?
Yes. It is a black dwarf.
Does fusion occur in white dwarf stars?
No. A white dwarf is the remnant of a star in which fusion as stopped.
Is a brown dwarf star on its way to becoming a black dwarf?
No. A brown dwarf is a star that has too low a mass to start nuclear fusion. A black dwarf is a former white dwarf, the remnant of a low to medium mass star that ran out of fuel in its core.
How are black dwarfs created?
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.
How hot is a nova?
The corresponding white dwarf needs to reach a temperature for nuclear fusion to occur, which is about 20 million degrees kelvin.
When its fusion stop a star will become either a black hole a neutron star or?
The other option is a white dwarf.
What causes stars to change during the white and black dwarf phases?
A white dwarf no longer produces energy through fusion but remains hot from the residual heat of the star it once was. It will radiate that energy away and slowly cool as a result, eventually becoming a black dwarf.
What changes are happing during the life cycle of a white dwarf?
The white dwarf will cool down till it becomes a black dwarf. If it's part of a close binary with a main sequence, giant or supergiant, the white dwarf can gain mass from the other star. This can start fusion of carbon in the white dwarf. Other fusion reactions quickly follow, causing it to explode. This is known as type 1a supernova.
What happens to a star when the outward force of fusion is less than the inward force?
the star collapses in on itself, and usually when the fusion stops it is in the last stages of its life as a giant or supergiant and forms a white dwarf made of the carbon left over from the second stage of helium to carbon fusion from the core of the star that takes place after the hydrogen to helium fusion. after the white dwarf is formed it will eventually cool off into a black dwarf which is basically a carbon corpse of a star
How can temperature either help fusion to occur or prevent fusion from occurring?
How can temperature either help fusion to occur or prevent fusion from occurring?
Will the sun become a brown dwarf?
No. A brown dwarf is a failed star, one that is not massive enough to start nuclear fusion. The sun is well above the threshold of fusion. When it dies it will become a white 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.
