Mar 4, 2022 · White dwarfs are what is left when stars like our sun have exhausted all of their fuel. They are dense, dim, stellar corpses — the last observable stage of evolution for low- and medium-mass...
White dwarfs typically have a radius just .01 times that of our own sun, but their mass is about the same. Stars like our sun fuse hydrogen in their cores into helium. White dwarfs are...
Despite 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 dwarfs. However, their small size makes them difficult to see directly unless they’re relatively close the Solar System.
