Professor Alexander Heger



  • Second semester 2016 (Day)


Stellar photometry; observing the stars; star formation; equation of state; reduced equations of stellar structure; polytropic stellar models; full equations of stellar structure; the main sequence; post-main-sequence evolution. Galactic morphology and stellar content; elliptical and spiral galaxies; large-scale structure of the Milky Way; dark matter; potential theory; galactic dynamics-orbits in spherical and axisymmetric potentials. Field trip. Astronomical data reduction.


On completion of this unit students will be able to:

  1. Understand the nature of stars - their life histories, how they produce energy, how they synthesise the chemical elements, and their ultimate fates;
  2. Build a simple polytropic numerical stellar model;
  3. Distinguish and discuss different types of galaxies;
  4. Understand the relationships between stellar evolution, galactic evolution, and the creation of the elements;
  5. Model computationally the motion of stars in galaxies;
  6. Understand the implications of the observed nature of galaxies for theories of the universe;
  7. Describe the morphology and kinematics of the Milky Way;
  8. Understand the significance of dark matter to galactic structure;
  9. Understand the use of optical telescopes for data collection;
  10. Write an observational research report.
