| Course description |
In the first semester, students are introduced to the
physics of stars and their influence on their galactic environment. The basic observational properties of stars are reviewed including the HR diagram, followed by a discussion of the physical structure of stars on the Main Sequence to their final states as exotic objects: white dwarfs, neutron stars, and black holes. The interactions of stars with their surroundings are described - namely HII regions, stellar winds and supernova remnants.
In the second semester, the course provides a broad introduction to the extragalactic universe. Topics include the properties of our own Milky Way Galaxy, the basic properties and evolution of other normal and active galaxies, basic stellar dynamics and the large scale structure and evolution of the Universe. |

Summary of Intended Learning Outcomes
Upon successful completion of this course, it is intended that the student will be able to :
1) Understand the physics behind the colour-magnitude diagram of stars.
2) Describe the physics of stellar structure, and apply hydrostatic equilibrium and radiative diffusion equations to get physical conditions and timescales.
3) Explain a star's energy production source and process, and describe how energy is transported out of a star.
4) Derive the equation of state of degenerate gas and describe the degeneracy pressure and support of white dwarfs and neutron stars.
5) Explain photoionization equilibrium, estimate the Stromgren radius and describe how the temperature and density of the intergalactic medium are measured.
6) Describe fluid dynamics equations, derive the sound speed and shock jump conditions, and explain the impact of stellar winds and supernovae on the intergalactic medium.
7) Correct for the effect on light of interstellar dust and the earth's atmosphere.
8) Describe in quantitative detail the morphology, content, structure and dynamics of the Milky Way and external galaxies.
9) Derive the basic formulae used to determine the velocity structure of the Milky Way, and to quantitatively describe the internal dynamics of stellar systems in general.
10) Explain how the masses of galaxies are deduced and how the distances to galaxies are established via the cosmological distance ladder.
11) Understand the physics of active galactic nuclei and be able to calculate order-of-magnitude estimates for key physical quantities.
12) Provide a quantitative description of the galaxy population at large, including galaxy number counts, luminosity functions, and clustering.
13) Describe in quantitative detail the evidence for an expanding and evolving Universe. Be able to derive and solve the basic equations describing the dynamics of the expansion.
