Astrophysics over a wide range of scales and wavelengths, gravitational wave astronomy and precision tests of gravitational theories.

Professor Freise talks about his research in gravitational waves :

Stars, the Sun and Exoplanets (aka HiROS)

Using asteroseismology and helioseismology, from the NASA Kepler Mission and the Birmingham Solar-Oscillations Network (BiSON) to study the Sun and stars (including exoplanet hosts).

X-Ray Binaries

Research in Galactic X-ray Astronomy: neutron star and black hole binary systems.
