How does a white dwarf form
WebAnswer: White dwarfs form after a low mass red giant (under 1.4 solar masses at the end of its main-sequence life) has used all its helium in the core. The core collapses under its own weight, but never gets hot enough for further fusion (since it is small). WebAs the hydrogen runs out, a star with a similar mass to our sun will expand and become a red giant. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called a supernova.

WebMay 7, 2015 · White dwarfs are stable because the inward pull of gravity is balanced by the electrons in the core of the star repulsing each other. With no fuel left to burn, the hot star radiates its remaining heat into the coldness of space for many billions of years.

WebSep 21, 2024 · Since white dwarfs cannot exceed a mass of 1.4 suns, they tend to form from stars below that mass. Then how exactly does a white dwarf exceed this limit and become a supernova? One way to increase a white dwarf’s mass is for it to steal material from another star. If a white dwarf happens to orbit another star, its gravitational pull may ...
