Jeans mass and length. Cloud fragmentation. Pre-main Structure of stars on the Main sequence and their respective lifetimes. Mass loss. p> Post main sequence evolution - Central fuel exhaustion and core contraction/collapse. Structure of evolving stars and evolutionary tracks on Hertzsprung-Russell diagram. |
Teaching and Learning Strategies |
|
In Person lectures The module will be delivered in person in 2021. Asynchronous learning materials (notes/videos/exercises etc) will be made available to students through the VLE. The module will have regular synchronous sessions in active learning mode. |
