The course is based on the theoretical development of the transfer of radiation through the atmospheres of stars, determining how the emergent spectrum may be used to determine the chemical composition of stars. Other aspects of stars related to their atmospheres are also examined; these include magnetic activity and stellar winds.
Upon successful completion, students will have the knowledge and skills to:
On completion of this course students will:
- Understand the physics and mathematics underpinning the radiative transfer equation
- Understand the significance of local thermodynamic equilibrium and non local thermodynamic equilibrium and the sources of opacity in stellar atmospheres.
- Understand the structure of stellar atmospheres and how this is determined through one-dimensional and three-dimensional solutions of the transfer equation.
- Understand the significance of the stellar parameters: the effective temperature, surface gravity and chemical abundance and how they are estimated.
- Be able to apply radiative transfer techniques to determine chemical abundances of stars in different environments such as the Galactic bulge and halo, the local group and the host stars of exo-planets.
6. Understand the effects of magnetic fields and the formation of emission lines in the winds of hot stars.

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.
10 hours per week consisting of 4 hours of lectures and tutorials and 6 hours of project work.
