Astronomy and Astrophysics

These areas provide a deeper understanding of nature through the study of extraterrestrial phenomena. Ground-based and space-based observational programs, theory, and data analysis all contribute to our program.

Our research in stellar astrophysics includes the study of brown dwarf stars, thermal and non-thermal processes in the sun and cool stars, convection in cool stars, stellar winds, and the late stages of stellar evolution, including the formation and evolution of white dwarfs. Data from the Chandra and Newton-XMM X-ray telescopes, the Hubble Space Telescope, the Far Ultraviolet Spectroscopic Explorer, YOHKOH, the Solar and Heliospheric Observatory, from the 2MASS, IUE and ROSAT archives are used to test and refine our theoretical ideas. Work in observational cosmology includes mapping the hydrogen content of small groups of galaxies using the VLA radio telescope.
