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 fusion occur in a black dwarf?
No. Fusion has long since ceased by the time a stellar remnant becomes a black dwarf.
Most stars are what kind of stars?
Red Dwarf stars. Massive stars are also quite common, but stars like that (e.g. R136a1) don't last very long.
What is the difference between red and brown dwarf stars?
Red dwarf stars are massive enough to undergo nuclear fusion, so they would burn a long time before they run out of fuel. Brown dwarves are not massive enough for nuclear fusion, so almost all of its light come from the time when the brown dwarf was formed. Over a long period of time, a brown dwarf would cool down into a gas giant similar to Jupiter.
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.
Why don't astronomers see greater numbers of dwarf stars?
because it takes a star long time to reach at the stage. That's wahy the astronomers can't see the dwarfs stars, and also these stars are small you will have to foucus on it little hard.
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.
Want happens when Red dwarf stars die?
Red dwarf stars have such long lifetimes that none of them ever have yet. Presumably, they will eventually go through the white dwarf phase before cooling entirely and becoming "black dwarfs".
What do stars do in their lifetime?
they live for a long time as regular sized stars then eventually they turn into red giants and explode then turning into a white dwarf
How long do dwarf stars live?
How long stars live depends primarily on their mass. Low mass stars live longer.A yellow dwarf star like the Sun has an expected lifetime of about 10 billion years on the main sequence, followed by a "red giant" phase that is considerably shorter, followed by a "white dwarf" (Type VII) phase lasting a very, very, very long time before the star eventually cools to the point it no longer emits light in the visible range, becoming a "black dwarf".Low-mass red dwarfs (below, say, 0.25 stellar masses) could conceivably live trillions of years. We don't really know exactly what will happen to them or how long they will live, because the universe itself is only about 14 billion years old, not nearly long enough for any red dwarfs to have died.
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.
What is a small hot star that is near the end of its life called?
There are small hot stars - White dwarfs, neutron stars but by furtue that they are hot, means they are not near the end of their lives. It takes a long long time for all the residual heat to escape into the Universe. So, there are NO hot stars near the end of it's life.
How long do dwarf live for?
They can live nearly or as long as other people.
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.
How long will a black dwarf star live?
It is unknown. Scientists belive that, since the life length of white dwarfs are so long, there aren't any black dwarfs in our universe yet.
Does fusion occur in a black dwarf?
No. Fusion has long since ceased by the time a stellar remnant becomes a black dwarf.
How long is the Sun's life expectancy?
It should "live" for about 5 billion years as it is, more or less. Then it will become a red giant star. Then it becomes a white dwarf. Finally it will "die" as a black dwarf.
What are Most stars are stars?
Red Dwarf stars. Massive stars are also quite common, but stars like that (e.g. R136a1) don't last very long.
