This course is an introduction to Astrophysics and is a study of stellar structure and evolution, galactic structure, and cosmology. Phenomena of interest include quasars, black holes, supernovae and the cosmic microwave background radiation. Special emphasis will be placed on those galactic phenomena, such as Galactic Cosmic Rays (GCRs) and Anomalous Cosmic Rays (ACRs), which have an impact on our heliosphere. Supporting topics include an overview of orbital mechanics and relevant physics, observation techniques, and nuclear physics.
