AST 309 Lecture Notes - Lecture 15: Low Mass, Protostar
Document Summary
Low-mass stars (like the sun) evolve much more slowly than massive stars. Stay on the main sequence a lot longer. May form in clustered regions (like most high mass stars) One, because it has started to form the protostar, it looks warmer. The lives of intermediate and low mass stars. Their fusion rates are slower, and their fuel capacity is bigger. For low mass stars, convection occurs throughout the entire star, not just at the center of the star like larger stars. Once uses all fuel, puffs up into red giant, left with a white dwarf at the center of a planetary nebula. No, they are still on the main sequence even after 14 billion years. Explosions big (supernova type i) and small (nova) Happens when mass from a high mass star transfers to a white dwarf.
