- White dwarf starsWhite star astronomy refers to the study of white dwarf stars, which are faint stars representing the endpoint of the evolution of intermediate- and low-mass stars1. White dwarf stars are characterized by a low luminosity, a mass on the order of that of the Sun, and a radius comparable to that of Earth1. Most white stars are hotter and more massive than our Sun, and use up their hydrogen fuel more quickly2. White dwarfs were once stars like our Sun, but they used up all the hydrogen fuel in their core2.Learn more:✕This summary was generated using AI based on multiple online sources.
