What is the difference between a White Dwarf star and a regular star?

i know that the White Dwarf star is bigger but what else?What is the difference between a White Dwarf star and a regular star?White dwarfs are actually smaller than most stars.

White dwarfs are about the size of Earth.



White dwarfs are made of a special type of matter, called degenerate matter. White dwarfs are extremely dense and can have a maximum mass of 1.4 solar masses, called the Chandrasekhar limit.

When a white dwarfs surpasses this mass, its collapses under its own weight and explodes, this is called a type 1a supernova.



Our sun will become a white dwarfs in about 6 billion yearsWhat is the difference between a White Dwarf star and a regular star?White dwarfs are actually smaller than most main sequence stars.



When a star like our Sun, ends its life, it won't do so in a supernova like the really massive stars will. It will shed off layers of its outer atmosphere. The remaining hot dense core, the 'corpse' if you will, of the Sun, will be called a white dwarf. No longer fusing elements and converting mass into energy at this point in time, it will slowly coo off to the ambient temperature of the space around it.What is the difference between a White Dwarf star and a regular star?A white dwarf is the remains of a somewhat normal star, like the Sun, that comes about after fusion no longer takes place within the star. It is very small and very hot for a very long time.What is the difference between a White Dwarf star and a regular star?
instead of a star going supernova, a White Dwarf star is a cooling star.



this will happen to our sun in about 4.5 - 5 Billion years. All life will be dead :'(
