How long do white dwarfs shine before they cool completely?
White dwarfs shine for billions of years before they cool completely. As they cool, they become dimmer and eventually fade into darkness, becoming black dwarfs. However, the process of a white dwarf cooling into a black dwarf takes 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 does it take for a white dwarf to cool?
It takes billions of years for a white dwarf to cool down and become a black dwarf. The cooling process is very slow, as the white dwarf gradually loses its thermal energy over time.
How long does it take for a white dwarf to become a black dwarf?
Billions of years - longer than the life of our universe has passed from now (21st century).
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.

What comes before white dwarf and after white dwarf?
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 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.
Are white dwarf stars white?
Yes. When they are first created after a "normal" star ends it life, they are white because they are very hot. Over time they will slowly cool and in doing so turn from white to yellow, to orange, then red, brown and eventually black.The cooling process takes billion of years. So long in fact that no white dwarf ever created, has had enough time to cool down completely.
Which star is the hottest red dwarf or white dwarf?
A white dwarf is the remnant of a star that has lost most of it mass. When it is formed it is very hot indeed but, as it now has insufficient mas to carry on fusion, it begins to cool down. For objects as massive as stars, even dwarfs, this cooling down takes a long time but eventually a white dwarf will cool down completely and become a black dwarf. Red dwarfs are never very hot as they have barely sufficient mass to effect fusion so don't do it very vigorously. However the fact that they go about their fusion slowly means they can maintain their meager temperatures for a long long time indeed. Some red dwarfs are older than the calculated age of the universe. (which is an interesting paradox) a nova What this person^^^^^ is really trying to say is that : The hottest star is white dwarf.
Can a male Rob dwarf hamster mate with a winter white dwarf hamster?
Yes, as long as you do it right.
What is a small star that only gives of faint light and are cool?
A small star that only gives off faint light and is relatively cool is likely a red dwarf star. These stars are much smaller and cooler than our Sun, but they are the most common type of star in the universe. Despite their dim appearance, red dwarfs can be very long-lived.
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.
How long will the sun be a red giant before it transitions into a white dwarf?
The sun will be a red giant for about 1 billion years before transitioning into a white dwarf.
How many black dwarfs are in the solar system?
None. Nor will there by any for a very long time. In about 7 billion years the sun will become a white dwarf, which ten, over the course of trillions of years, cool to become a black dwarf. At that point our solar system (or what is left of it) will have exactly one black dwarf
