WebOnly the gradual depletion of hydrogen as it is transformed into helium in the core slowly changes the star’s properties. The 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. WebOftentimes, many stars are born from the same nebula, and remain close together in a star cluster. For that reason, many of the stars in a cluster have similar chemistry and were born at roughly the same time. Some clusters contain very old stars, while others are far younger, providing astronomers with a laboratory for understanding stellar ...
