Theoretical Astrophysics

Research in the Theoretical Astrophysics division utilizes both physical analysis and mathematical modeling to understand astronomical systems. A broad range of topics is investigated, including the formation, structure, and evolution of stars, the properties of atoms and molecules in interstellar space, the structure and properties of accretion systems, high-temperature plasmas, the formation and evolution of planetary systems, both solar and extrasolar, the formation of galaxies, clusters, and quasars in the universe, and theories of the early universe.
