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.
Does a star that has no fuel but glows faintly is a black dwarf?
A star that has burned out and no longer has fuel to sustain nuclear fusion in its core is called a white dwarf, not a black dwarf. A white dwarf is the remnant core of a low to medium mass star after its outer layers have been ejected. Over time, a white dwarf will cool down and eventually become a black dwarf, but this process takes billions of years.
What is a cooled white dwarf star that is extremely dense?
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.
Can a mid sized star become a or a black dwarf?
Yes, a mid-sized star can eventually become a white dwarf or a black dwarf. After exhausting its nuclear fuel, the star sheds its outer layers to form a planetary nebula, leaving behind a white dwarf. Over trillions of years, a white dwarf may cool and fade into a black dwarf, although this process would take longer than the current age of the universe.
Why would a white dwarf become a red dwarf?
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
Are white dwarf stars always white?
No in the life cycle of a star, a white dwarf can cool and become a black dwarf
What is another name for a small old cool star?
white dwarf
What is a star formed from a white dwarf that has lost its energy?
A white dwarf is the last stage of 97% of star evolution. A white dwarf will eventually cool down, and become a "black dwarf". Black dwarves are not expected to exist yet; to cool down to that level, it would take longer than the current age of the Universe.
Is a white dwarf an old dense cool star?
A white dwarf is the remains of an old star, but they still remain very hot and will continue to shine as a white dwarf for many millions of years until they gradually cool off to become black dwarfs. They are very dense.
Is a dwarf star and a white dwarf the same thing?
No. A dwarf star is a small star. A white dwarf is just one particular type of dwarf star, but there are other types.
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.
Is the white dwarf the biggest star?
No a white dwarf is a small compact star.
Does a star that has no fuel but glows faintly is a black dwarf?

What is a cooled white dwarf star that is extremely dense?
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.
What is the final stage of a yellow star?
The final stage of a yellow star like our Sun is the formation of a planetary nebula. This occurs when the star sheds its outer layers into space, leaving behind a hot core called a white dwarf. Over time, the white dwarf will cool and fade away.
Can a mid sized star become a or a black dwarf?
Yes, a mid-sized star can eventually become a white dwarf or a black dwarf. After exhausting its nuclear fuel, the star sheds its outer layers to form a planetary nebula, leaving behind a white dwarf. Over trillions of years, a white dwarf may cool and fade into a black dwarf, although this process would take longer than the current age of the universe.
Is a dead star the some as a black dwarf?
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.
