Learning outcomes

Students who successfully complete this unit will be able to:

  • Explain the classification schemes of stars, their physical parameters and the importance of the HR diagram
  • Explain and summarise the mechanism of star formation and the evolution of stars from the main sequence through to the RGB and AGB phase
  • Appraise and state the processes and properties of high mass stellar remnants, including supernovae, planetary nebulae, white dwarfs, neutron stars and black holes
  • Solve mathematical problems related to the physical processes that underlie stellar properties and evolution
  • Explain and summarise stellar astrophysical concepts in a non-technical manner understandable to the general public
  • Design and create a research project on an astronomy topic, assessing and critiquing current knowledge, using credible sources of astronomical information, data and research articles
