The Life of a Star
... 2. Describe the differences between the life of a low-mass star and that of a star 10 times the Sun’s mass. Low-mass stars cool down and swell up into a red giant. Outer layers drift away and the star shrinks to become a white dwarf which will cool and fade away. High-mass stars swells into a red su ...
