Dying low-mass stars
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. WebBecause the star’s mass is relatively low, it cannot push its core temperature high enough to begin another round of fusion (in the same way larger-mass stars can). The core continues to shrink until it reaches a density equal to nearly a million times the density of …
