Student Learning Outcomes
Students will be able to describe how astronomers measure stellar properties such as luminosity, temperature, radius, mass, and composition.
Students will be able to explain the Hertzsprung-Russell (H-R) diagram and its role in understanding stellar evolution.

Students will be able to compare and contrast the evolutionary paths and ultimate fates of low-mass, intermediate-mass, and high-mass stars.
Students will be able to quantitatively and qualitatively describe the physics and observational properties of stellar remnants such as white dwarfs, neutron stars, and black holes.
