Jacques Richer

Jacques Richer is a Researcher affiliated with the Department of Physics at Université de Montréal, part of the Faculty of Arts and Sciences. He specializes in stellar evolution, atomic diffusion processes in stars, and radiative acceleration effects. His work focuses on developing the Montreal stellar evolution code (xevol), which models element diffusion and radiative forces in stars like HgMn and AmFm types. He collaborates with institutions such as Meudon Observatory and the University of Moncton. Richer contributed to the Centre de Recherche en Astrophysique du Québec (2008–2017), a strategic research initiative involving over 40 researchers. His research bridges stellar structure, nucleosynthesis, and cosmological lithium abundance studies, addressing topics like Big Bang nucleosynthesis discrepancies and stellar transport mechanisms.

Key projects include studying lithium depletion in Pop II stars and the impact of mass loss on abundance anomalies. His publications span topics from bidomain cardiac modeling (2005) to α-element effects on stellar isochrones (2012). Richer’s work emphasizes precision in radiative acceleration calculations and the role of turbulent transport in stellar interiors.
