Question
This week, we round out the details of stellar evolution, from birth to death. To give us an organized and clear picture of the basic outline of a star's life, we are going to fill out the cartoon picture of a low-mass and a high-mass star's life. Below is a list of the stages of evolution for a low-mass star and a high-mass star:
High-mass Stars
Low-mass Stars
0: proto-star
0: proto-star
1: main-sequence
1: main-sequence
2: yellow giant
2: red giant
3: red supergiant
3: yellow giant
4: supernova
4: 2nd red giant or red supergiant
5: BH or NS
5: planetary nebula
6: white dwarf
Select one of the stages in either a low-mass or a high-mass star's life (check before you select, to make sure no-one (or as few people as possible!) has not written about it yet. Since we have enough students for duplicates, do a stage with no duplicates if possible, otherwise, proceed.) If there is fusion, describe WHAT is being fused (if no fusion, explain the source of light) If there is fusion, describe WHERE fusion is occurring (if no fusion, state this)
