What else can I help you with?
Does fusion occur in a black dwarf?
No. Fusion has long since ceased by the time a stellar remnant becomes a black dwarf.
How does the black hole stage transitions into the next stage?
Basically there is no "next stage". Well, it is believed that a black hole will evaporate, but that will take a long, long time.
Why is the black dwarf the last stage?
Because the stellar remnant has no more fuel to burn and any residual heat left over from when it was a white dwarf has left. In fact it should just be called a cold rock. See related question.
What is the size of the black dwarf?
A black dwarf is any stellar remnant, that has cooled completely, so that no radiation is emitted. They - at the moment - do not exist, as the Universe has not been around long enough for any stellar remnant to cool to this state. A black dwarf would - if it existed - be anywhere from the size of a city (Neutron star) up to 1.4 times larger than the Earth.
How long do black dwarf stars live for?
it depends on the conditions it could last as little as 100 years or up to 1 million years oh and are you sure you are talking about a brown dwarf because i do not think those exist but i don't know
Does the black dwarf have a satellite?
We don't think there are any black dwarf stars yet. There hasn't been long enough for them to cool to the "black" stage. When there has been, then presumably some of them will have satellites.
How long does a black dwarf last?
As long as the Universe exists. See related question for more information.
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 does a white dwarf die?
A white dwarf does not die in the traditional sense as it is already the end stage of a low-mass star's life cycle. However, over a very long period of time (trillions of years), a white dwarf will cool and fade away, eventually becoming a black dwarf.
How long is the yellow dwarf stage in the Sun's life?
The sun will spend a total of about 10 billion years as a yellow dwarf. A little less than half of that time has already passed.
How big can a black dwarf planet get?
A black dwarf is not a planet; it is the remnant of a long dead star that has cooled. A black dwarf would range from about 7,000 to 17,000 miles in diameter.
Does fusion occur in a black dwarf?
No. Fusion has long since ceased by the time a stellar remnant becomes a black dwarf.
What is a dim star that forms from a collapsed red giant?
It is called a white dwarf. It is the penultimate stage of a star the size of the Sun, which progresses with age from a yellow or orange star, to a red giant, to a white dwarf, and ultimately (after an immensely long period of time) a black dwarf. (There are no confirmed black dwarf stars because their formation may take much longer than the current age of the universe.)
How does the black hole stage transitions into the next stage?
Basically there is no "next stage". Well, it is believed that a black hole will evaporate, but that will take a long, long time.

When a star becomes a black dwarf it?
In that case, it will basically stop emitting any radiation. No star has had time so far to become a black dwarf - the Universe is too young for that. This is because it takes a white dwarf a long, long time to cool down.
