How do white dwarfs form
WebSep 26, 2024 · Stars smaller than a quarter the mass of the sun collapse directly into white dwarfs. White dwarfs no longer burn fusion at their center, but they still radiate heat. WebNov 18, 2024 · What are white dwarfs and how do they form? Life cycle of a star. Credit: NASA. When massive stars like the Sun or red dwarfs like our nearest neighbor Proxima Centauri approach the end of their lives, they transform into white dwarfs. As a result, they will end up like the overwhelming majority of stars in our galaxy and beyond.
