Atomic Diffusion in Stars - Alecian, Georges

. .

Résumé :

Prof. Georges Michaud has been a Professeur ?m?rite at the Universit? de Montr?al since 2005. He has worked in their physics department as a professor since 1969, after obtaining his PhD in astronomy from the California Institute of Technology. He is the recipient of the 2006 C.S. Beals Award from the Canadian Astronomical Society and has been a member of the Royal Society of Canada since 1992. He was awarded the ?Steacie Prize of the NRC of Canada in 1980 and the M?daille Janssen? of the Acad?mie des sciences de Paris in 1982.

Dr. Georges Alecian is a CNRS Research Director Emeritus at CNRS-Observatoire de Paris (LUTH). His main fields of research are stellar physics, theory and modeling of transport processes of elements and atomic diffusion. He was director of Laboratory/Department (LAEC/DAEC, CNRS-Observatoire de Paris, Universit? Paris-Diderot) from 1996 to 2001, and he has been member of the CoRoT space mission scientific council since 1998. ?Since 2012, he is foreign member of the National Academy of Sciences of the Republic of Armenia (NAS RA).

Dr. Jacques Richer obtained his PhD in astrophysics from the Universit? de Montr?al in 1993, and has been a research assistant in the physics department's astronomy?group since then. He has also been a scientific computing analyst and consultant with various Qu?bec academic organizations (CERCA, RQCHP, and finally, Calcul Qu?bec) from 1997 to 2015.
