Theoretical Astrophysics Program

Theoretical Astrophysics Program

Theoretical Astrophysics Program

In 1985, the University of Arizona consolidated its traditional and long-standing strength in astronomy and planetary sciences through an interdisciplinary program in theoretical astrophysics that includes the departments of Physics, Astronomy, Planetary Sciences (LPL), and Applied Mathematics Departments, as well as the National Optical Astronomy Observatory. The Theoretical Astrophysics Program (TAP) administers a Monday colloquium series, graduate student research and recruitment prizes, a postdoctoral fellowship, and a visitor program.

Erik Asphaug

Erik Asphaug

Professor

I study giant impacts that dominate the late stage of planet and satellite formation, such as that which formed the Moon, that can explain why planets are so diverse and...

Joe Giacalone

Professor

Dr. Giacalone's core research interests include understanding the origin, acceleration, and propagation of cosmic rays, and other charged-particle species in the magnetic fields of space, and general topics in space...

William Hubbard

Professor Emeritus

Dr. Hubbard's research focuses on studies of the structure and evolution of Jupiter, Saturn, and extrasolar giant planets (EGPs). Originally as a Co-Investigator with the proposed INSIDE Jupiter orbiter and...

Kristopher Klein

Associate Professor

Dr. Klein's research focuses on studying fundamental plasma phenomena that governs the dynamics of systems within our heliosphere as well as more distant astrophysical bodies. He has particular interest in...

Jozsef Kota

Senior Research Scientist (Retired)

Dr. Kota's research interest is centered around energetic particles, solar wind, and magnetic fields in the Heliosphere. He conducts theoretical and numerical studies on galactic and anomalous cosmic rays, as...

Renu Malhotra

Regents Professor
Louise Foucar Marshall Science Research Professor

Professor Malhotra's research spans orbital dynamics in the solar system and in exo-solar planetary systems. Current topics of research are: theory of orbital resonances, long term stability and chaos in...

Isamu Matsuyama

Professor

Dr. Matsuyama is interested in the physics of planetary interiors and evolution, with an emphasis on understanding the processes that led to the extraordinary diversity of the solar system. He...
