WebDec 28, 2024 · The mass of that white dwarf depends a lot on how massive the star was initially. The more massive the star, the more massive the white dwarf. But this leads to a paradox! The lowest mass white dwarfs we see are less than 0.3 times the Sun's mass; we call these Extremely Low Mass white dwarfs, or ELMs. Although white dwarfs are known with estimated masses as low as 0.17 M☉ and as high as 1.33 M☉, the mass distribution is strongly peaked at 0.6 M☉, and the majority lie between 0.5 and 0.7 M☉. The estimated radii of observed white dwarfs are typically 0.8–2% the radius of the Sun; this is comparable to the Earth's radius of approximately 0.9% solar radius.
