Mr. Keszthelyi’s research focuses on the evolution of magnetic hot massive stars. MESA (Modules for Experiments in Stellar Astrophysics) and the Geneva stellar evolution codes are used for the model computations. Spectropolarimetric observations are obtained using the CFHT (Canada-France-Hawaii Telescope). Mr. Keszthelyi investigates the impact of magnetic fields on massive star evolution, and his model calculations account quantitatively for the evolution of the magnetic field.
