Learning Objective
I can describe the life cycle of stars and their classification based on the Hertzsprung-Russell diagram.
- 1
Stars are born in nebulae, where gravitational collapse initiates nuclear fusion.
- 2
The Hertzsprung-Russell diagram classifies stars by luminosity and surface temperature.
- 3
Massive stars end their lives in a supernova explosion, potentially forming a neutron star or black hole.
