Mr. Keszthelyi’s research focuses on the evolution of magnetic hot massive stars. Stellar evolution models are computed and spectropolarimetric observations are acquired. For the model calculations the MESA (Modules for Experiments in Stellar Astrophysics) code is used, while 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 also account quantitatively for the evolution of the magnetic field.
