159 Stellar Mass (62/35) -- Introduction to Astronomy

159 Stellar Mass The type and life of the new star depends on the initial amount of material present: its stellar birth weight. Astronomers group stars as Low-mass , <1.33 m ⊙ ; Intermediate-mass , 1.33 m ⊙ to 4 m ⊙ ; and High-mass :>4 m ⊙ . (Recall m ⊙ refers to the mass of the Sun, the Sun = 1 m ⊙ ) Each of these star groups has different lives and deaths. In this module, we will examine low- and high-mass stars.
