There is no fuel for a white dwarf. A white dwarf is a remnant of a star in which fusion has stopped. There is, however, quite a bit of leftover heat, so the white dwarf still glows.

Explain the role of nuclear fusion in the life cycle of a star?
It's the energy source for all stars (until their fuel is used up - white dwarf stage).
What happens if you touch a white dwarf?
theoraticly? you would burn because of the heat buts it is impossible because you wouldn't be able to get close enough to one with out either being sucked into it and being bunred as fuel or dieing of loss of oxygen.
A star that has collasped after using its fuel?
A star, after using all of it's fuel explodes. We call this a super nova, and after this the star will either become a black dwarf star (or maybe a white dwarf) or it will collapse in on its self creating a black hole.
What is the evolutionary end of red giants?
When a red giant runs out of its fuel - helium - it will blow off its outer layers while the inner core collapses to form a white dwarf. The latter will gradually radiate away its energy to become a black dwarf.
Which progression do astronomers expect our sun to follow as it runs out of fuel?
When the sun runs out of fuel it is expected to turn into a red supergiant engulfing earth. Then it is supposed to shrink into a white dwarf.
When does a white dwarf run out of fuel?
A white dwarf is the remnant of a star that has already run out of fuel.
Is a dwarf star one that has no fuel to make its own energy?
Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.
Can a white dwarf that has no fuel make its own energy?
No. The energy of a white dwarf is simply residual heat.
A star that has collapsed after using its fuel?
White Dwarf
A star that has colloasped after using a fuel?
White dwarf.
What is a star that collapse after using its fuel?
white dwarf
When a star has no fuel left and its outer layers escape into space what is its remaining core called?
When the layers escape into space, this is classified as a planetary nebula. What usually is left behind is a white dwarf.
Will Sirius b become a supernova?
No. It's a white dwarf, meaning that it has no more fuel left for such things.
Explain the role of nuclear fusion in the life cycle of a star?
It's the energy source for all stars (until their fuel is used up - white dwarf stage).
How a star becames a white dwarf?
A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
Is a white dwarf star is one that does not have fuel to make is own energy?
That's called a "black dwarf". Such objects are hypothetical; they are not expected to exist yet, since it takes a white dwarf longer, to cool down to a black dwarf, than the current age of the Universe.
Why is a white dwarf considered a dead star?
A white dwarf is not considered a "dead star." It is considered a dying star, but not dead yet. A white dwarf is at its smallest state and could become a supernova when its center runs out of fuel to burn.
