- Second semester 2017 (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. Astronomical data reduction.
On completion of this unit students will be able to:
- Understand the nature of stars - their life histories, how they produce energy, how they synthesise the chemical elements, and their ultimate fates;
- Build a simple polytropic numerical stellar model;
- Distinguish and discuss different types of galaxies;
- Understand the relationships between stellar evolution, galactic evolution, and the creation of the elements;
- Model computationally the motion of stars in galaxies;
- Understand the implications of the observed nature of galaxies for theories of the universe;
- Describe the morphology and kinematics of the Milky Way;
- Understand the significance of dark matter to galactic structure;
- Understand the use of optical telescopes for data collection;
- Write an observational research report.
