WebFeb 19, 2024 · Why do white dwarfs shrink as they gain mass? The size of a star is a balance between pressure and gravity. Gravity pulls the outer layers of the star inward. So, as you add mass to a white dwarf, the gravity increases, but the pressure only changes a small amount. Gravity wins and the star shrinks. WebWhite 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.
