Description of Research

Summary Statement of Research Interests

Professor Rhodes leads an active program in both ground- and space-based observational helioseismology. One of the pioneers in this field of solar physics he is a NASA-selected Co-Investigator on the Solar Oscillation Investigation (SOI). The SOI-Michelson Doppler Imager flys onboard the NASA-ESA Solar and Heliospheric Observatory spacecraft. Professor Rhodes is the Principal-Investigator for the 60-Foot Solar Tower at Mt. Wilson Observatory and the High Degree Helioseismic Network (HiDHN). This network consists of a second station in Ukraine, at the Crimean Astrophysical Observatory. HiDHN provides nearly continuous observations of the sun during the summer months.
