WebJan 17, 2024 · But when massive stars die, they go out in all their glory.Their huge size, means there's enough gravitational pressure to not only fuse hydrogen, but also helium. … WebThe ultimate life and death of a star depends on its initial mass. Today we will look at the life of low-mass stars, which are those with mass less than about 2 times the mass of the Sun (less than 2 solar masses). So the Sun is a low-mass star. All such stars follow the same basic pattern.
WebLow-mass stars are those that end up as white dwarfs. are those that end their lives in a supernova. Our Sun is an example of a low-mass star; Betelgeuse is an example of a high-mass star.
