Undergraduate Faculty of Science
Leader(s): Professor John Lattanzio
Clayton Second semester 2009 (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: understand the nature of stars - their life histories, how they produce energy, how they synthesise the chemical elements, their ultimate fates; be able to build simple polytropic numerical stellar models; be able to distinguish and discuss the different galactic types; understand the relationships between stellar evolution, galactic evolution, and the creation of the elements; be able to model computationally the motion of stars in galaxies; understand the implications of the observed nature of galaxies for theories of the universe; be familiar with the morphology and kinematics of the Milky Way; understand the significance of Dark matter to galactic structure; be able to use a large research-level telescope, including for data collection and analysis.
