A white dwarf forms when a star like our Sun exhausts its nuclear fuel and undergoes a series of changes in its life cycle. After expanding into a red giant, the star sheds its outer layers, creating a planetary nebula, while the core remains and contracts under gravity. This hot, dense core is what becomes the white dwarf, primarily composed of carbon and oxygen, which eventually cools and dims over billions of years. The white dwarf no longer undergoes fusion reactions and will ultimately fade away as it radiates its remaining heat into space.
What else can I help you with?
What is the radius of a white dwarf with a mass of 1.5 solar units?
Such a white dwarf could not exist. Above 1.4 solar masses a white dwarf will collapse to form a neutron star.
What is the next stage after The white dwarf stage?
the next stage of a white dwarf is the black dwarf which is form when the degenerate electron slowly cools down by thermal radiation but the time required for a white dwarf to become a black dwarf is bigger than the current age of universe so the evidence of a black dwarf isn't found yet
Which is the correct order - white dwarf or red?
The correct order is red giant followed by white dwarf. A red giant is a stage in the life cycle of a star where it has expanded and cooled. After the red giant phase, the star sheds its outer layers and the core collapses to form a white dwarf.
The sun will eventually end up as a?
white dwarf star
Is a white dwarf smaller than a red dwarf?
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.

What two stars can form a nova?
A Main Sequence star and a White Dwarf.
What is the singular possessive form of dwarf?
The possessive form of the noun dwarf is dwarf's.
What gas is being used as a fuel source for the white dwarf?
The gas being used as a fuel source for white dwarfs is primarily hydrogen. During nuclear fusion reactions in the core of a white dwarf, hydrogen atoms are fused together to form helium, releasing energy in the process.
Carbon and what other element make up a white dwarf?
Carbon and oxygen are the two main elements that make up a white dwarf star. These elements are the end products of nuclear fusion in the core of the star before it exhausted its nuclear fuel and collapsed to form a white dwarf.
What type of stars has a low temperature and high luminosity?
A white dwarf.A white dwarf.A white dwarf.A white dwarf.
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.
What is the singular possessive for dwarf?

Are white dwarf stars always white?
No in the life cycle of a star, a white dwarf can cool and become a black dwarf
