WebDespite their name, white dwarfs can range in color from blue-white to yellow, depending on how hot they are. They are common: most stars will eventually become white … 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. A white dwarf, then, packs …
WebOnce the Sun stops fusing helium in its core and ejects its layers in a planetary nebula in about 8 billion years, it will become a white dwarf and, over trillions of years, eventually will no longer emit any light. WebSome stars become white dwarfs near the ends of their lifetimes. A star in this phase of its existence is superdense; it can have the mass of the sun yet be only as large as the Earth. One of the first white dwarf stars ever observed is the companion to Sirius, in the constellation Canis Major. The two stars, which ...
