An introduction to the physics of the stars, including stellar structure, the theory of the main sequence and the Hertzprung-Russell diagram, stellar birth, and the endstages of stellar life (white dwarfs, neutron stars and black holes.) We will also examine galaxy formation, the inflationary Big Bang theory, and the influence of dark matter and dark energy on the structure and ultimate fate of the universe.
