This course provides an introduction to stellar structure, evolution, and atmospheres. It covers the basic physical processes that govern the behaviour of stars, including hydrostatic equilibrium, thermal balance, nuclear energy generation, and radiation transport, the application of these principles to modeling the life cycle of stars from birth to the main sequence to death, and the development of tools to deduce stars' physical properties from the light they emit.
This course is co-taught with undergraduate students but assessed separately.
Upon successful completion, students will have the knowledge and skills to:
- Explain the concepts of hydrostatic balance, equations of state for stellar matter, transfer of heat through stars, stellar nucleosynthesis, and radiation transport, and perform calculations using these concepts;
- Calculate the internal structures of stars at a variety of levels of approximation;
- Describe the life cycles of stars from birth to death, and how these cycles depend on stellar mass;
- Explain the basic theory of stellar spectra, and use this theory to interpret the observed spectra of stars;
- Work effectively as part of a group;
- Read, interpret, and critically analyse professional research literature in the areas of stars;
- Identify unsolved problems in stars, and propose research approaches that could be used to address them.
- 6 problem sets (40) [LO 1,2,3,4,5]
- Final exam (40) [LO 1,2,3,4]
- Critical reflection on research literature, delivered in written and oral form (20) [LO 6,7]

The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.
The expected workload will consist of approximately 130 hours throughout the semester including:
- Face-to face component which may consist of 3 hours of lectures (1x2 hour lecture plus 1x1 hour lecture) and 1 x 1 hour tutorial per week
- Approximately 96 hours of self-study which will include preparation for lectures, presentations and other assessment tasks (average 5 hours per week of problem sets and 3 hours per week of work on the literature analysis).
