WebThe mass of a star determines exactly where it falls on the main sequence. As Figure 21.12 shows, massive stars on the main sequence have high temperatures and high luminosities. Low-mass stars have low temperatures and low luminosities. Objects of extremely low mass never achieve high-enough central temperatures to ignite nuclear reactions. WebFigure 23.6 Structure of an Old Massive Star. Just before its final gravitational collapse, the core of a massive star resembles an onion. The iron core is surrounded by layers of silicon and sulfur, oxygen, neon, carbon mixed with some oxygen, helium, and finally hydrogen. Outside the core, the composition is mainly hydrogen and helium.

WebSep 1, 2024 · Evolution. All stars, irrespective of their initial mass, spend the majority of their life consuming hydrogen. This period, which can last tens of billions of years, is the most stable time in the stellar lifecycle. The lifetime of a star depends largely on its mass. Somewhat counter intuitively, the more massive a star is the shorter its lifetime! WebThe star must now confront the fact that its death is near. We will discuss how stars like this end their lives in The Death of Stars, but in the meantime, Table 22.4 summarizes the stages discussed so far in the life of a star with the same mass as that of the Sun.
