ASTR 101 Introduction To Astronomy

This course will explore the history and heritage of modern astronomy. Our task is to understand how astronomers gain information about the solar system, the planets, individual stars, the galaxies and, indeed, the universe. We shall see how basic physical principles can be used to determine intrinsic stellar properties, and we shall discuss some of the present-day ideas relating to the formation and evolution of the stars.  


ASTR 201 Solar System Astronomy

This course is concerned with the description of the fundamental properties of our solar system. Topics include planetary interiors, surface structures and atmospheres: asteroids, comets and meteorites; the formations of planetary systems.


ASTR 202 Stars and Galaxies

In Astronomy 202 we shall examine a few of the fundamental ideas that define modern astronomy. Our task is to understand how astronomers gain fundamental and physical data about individual stars and galaxies. We shall also see how the observational data can be used to constrain theoretical models of stellar and galactic structure.


ASTR 302 Structure & Evolution of Sun

The physics of stellar interiors and stellar evolution will be reviewed with the Sun as the central example. The story of our Sun from formation, through its main sequence phase to its final white dwarf stage will be investigated and the long-term evolution of the solar system will be discussed. The specific topics to be covered will include: gravitational collapse, the formation of stars, quasi-static equilibrium, the equations of stellar structure, nuclear energy generation, properties of white dwarf stars, properties of degenerate matter and the Lane-Emden equations of polytropic structures.
