Do all white dwarfs [(stars] always turn into diamonds?
A white dwarf, also called a degenerate dwarf, is a small star composed mostly of electron-degenerate matter. Because a white dwarf’s mass is comparable to that of the Sun and its volume is comparable to that of the Earth, it is very dense. Their faint luminosity comes from the emission of stored heat.[1] They comprise roughly 6% of all known stars in the solar neighborhood.[2] The unusual faintness of white dwarfs was first recognized in 1910 by Henry Norris Russell, Edward Charles Pickering and Williamina Fleming;[3], p. 1 the name white dwarf was coined by Willem Luyten in 1922.[4] White dwarfs are thought to be the final evolutionary state of all stars whose mass is not too high—over 97% of the stars in our Galaxy.[5], §1. After the hydrogen-fusing lifetime of a main-sequence star of low or medium mass ends, it will expand to a red giant which fuses helium to carbon and oxygen in its core by the triple-alpha process. If a red giant has insufficient mass to generate the core tempera
