Theoretical Astrophysics

The goal of theoretical astrophysics is to provide physical and conceptual understanding of the diverse systems that represent our universe. To emphasize the different approach needed for developing a theoretical framework, this course is organized into themes of governing physical principles. For each of the three main themes (gravity, gas physics and quantum physics), we start with fundamental principles and then discuss applications in various astronomical contexts. We will show how application of simple physical laws can explain the observed properties of an astounding range of astronomical objects!
