Chapter 23.1 - The Death of Low-Mass Stars
- Learning Objectives
  - Describe the physical characteristics of degenerate matter and explain how the mass and radius of degenerate stars are related
  - Plot the future evolution of a white dwarf and show how its observable features will change over time
  - Distinguish which stars will become white dwarfs
- The number of stars decreases as mass increases
  - Really massive stars are rare
Chapter 23.2 - Evolution of Massive Stars: An Explosive Finish
- Learning Objectives
  - Describe the interior of a massive star before a supernova
  - Explain the steps of a core collapse and explosion
  - List the hazards associated with nearby supernovae
Chapter 23.3 - Supernova Observations
- Learning Objectives
  - Describe the observed features of SN 1987A both before and after the supernova
  - Explain how observations of various parts of the SN 1987A event helped confirm theories about supernovae
Chapter 23.4 - Pulsars and the Discovery of Neutron Stars
- Learning Objectives
  - Explain the research method that led to the discovery of neutron stars, located hundreds or thousands of light years away
  - Describe the features of a neutron star that allow it to be detected as a pulsar
  - List the observational evidence that links pulsars and neutron stars to supernovae
Chapter 23.5 - The Evolution of Binary Star Systems
- Learning Objectives
  - Describe the kind of binary star system that leads to a nova event
  - Describe the type of binary star system that leads to a type Ia supernovae event
  - Indicate how type Ia supernovae differ from type II supernovae
