Geraldine Peters

Geraldine Peters is a Research Professor of Physics and Astronomy at USC specializing in binary star systems and stellar astrophysics. Her research investigates mass transfer processes, circumstellar material, and chemical abundances in interacting binaries using space-based observatories.

Key contributions include identifying hot subdwarf companions in Be star systems, modeling accretion structures in Algol binaries, and analyzing cyclic bipolar winds in interacting systems. Peters utilizes data from Hubble, Kepler, GALEX, and FUSE missions to study stellar evolution in binary environments.

She holds leadership roles in the International Astronomical Union, chairing the Working Group on Active B Stars and serving on Division G steering committee. Peters has received NASA group achievement awards and edited IAU symposium proceedings on OB star astrophysics.
