Stellar Evolution

Stellar Evolution. The birth, Life and Death of stars Assigned Reading: up to Chapter 12. A main sequence star is the one which is supported by hydrogen fusion. The main sequence exists because stars balance their weight with energy outflows, produced by nuclear fusion in their core.

Stellar evolution and star clusters

Stellar evolution and star clusters. Key variable is mass of star directly measured only for binary stars, but it determines position on main sequence. Cluster ages. Main-sequence luminosity increases much faster than mass therefore massive stars use up their fuel much faster
