About

Geoffrey Clayton is a Professor at Louisiana State University, USA. His research focuses on the astrophysics of supernovae, carbon stars, and white dwarf mergers, as evidenced by his recent publications, including studies on the oxygen-rich supernova 1995N and the dust declines in R Coronae Borealis stars. He also investigates the correlations of hydrogen-deficient carbon stars and the implications of white dwarf merger outcomes.
