Organizing and summarizing search results for youWhite dwarf stars are characterized by:- A low luminosity
- A mass on the order of that of the Sun
- A radius comparable to that of Earth
- A very dense core composed mostly of electron-degenerate matter
- No residual nuclear energy source
- No fusion taking place in the star
- A radius just .01 times that of our own sun, but their mass is about the same
- Burning up all of the hydrogen they once used as nuclear fuel
3 Sources White dwarfs: Facts about the dense stellar remnants | Space
Main-sequence stars, including the sun, form from clouds of dust and gas drawn together by gravity. How the stars evolve through their lifetime depends on their mass. The most massive stars, with eight times the mass of the sun or more, will never become white dwarfs. Instead, at the end of their lives, … See more

White dwarf - Wikipedia
The first white dwarf discovered was in the triple star system of 40 Eridani, which contains the relatively bright main sequence star 40 Eridani A, orbited at a distance by the closer binary system of the white dwarf 40 Eridani B and the main sequence red dwarf 40 Eridani C. The pair 40 Eridani B/C was discovered by William Herschel on 31 January 1783. In 1910, Henry Norris Russell, Edward Charles Pickering and Williamina Fleming discovered that, despite being a dim star, 40 Eridani B …
