Ren\u00e9 Doyon est professeur au D\u00e9partement de physique de l\u2019Universit\u00e9 de Montr\u00e9al, et on lui a confi\u00e9 une Chaire de recherche du Canada (niveau 1) en astrophysique exp\u00e9rimentale et science exoplan\u00e9taire. Il est \u00e9galement directeur de l\u2019Institut Trottier de recherche sur les exoplan\u00e8tes et de l\u2019Observatoire du Mont\u2011M\u00e9gantic.<\/p>\n\n\n\n
Pionnier de l\u2019infrarouge, M. Doyon a \u00e9labor\u00e9 des instruments d\u2019avant\u2011garde pour la d\u00e9tection et la caract\u00e9risation des plan\u00e8tes situ\u00e9es \u00e0 l\u2019ext\u00e9rieur du syst\u00e8me solaire. Il est le chercheur principal et le coordonnateur de l\u2019ensemble de la contribution canadienne au t\u00e9lescope spatial James\u2011Webb lanc\u00e9 par la NASA en 2021.<\/p>\n\n\n\n
M. Doyon consacre tout son savoir \u00e0 la cr\u00e9ation d\u2019instruments ultrasp\u00e9cialis\u00e9s pour l\u2019\u00e9tude d\u2019exoplan\u00e8tes, d\u2019\u00e9toiles et de naines brunes, ce qui m\u00e8ne \u00e0 des d\u00e9couvertes transformatrices. Le concept novateur qu\u2019il a propos\u00e9 consiste \u00e0 att\u00e9nuer l\u2019\u00e9blouissement caus\u00e9 par la lumi\u00e8re stellaire pour d\u00e9tecter des plan\u00e8tes auparavant invisibles. Les techniques mises au point par son \u00e9quipe ont permis de capturer les toutes premi\u00e8res images d\u2019un syst\u00e8me plan\u00e9taire en orbite autour d\u2019une \u00e9toile autre que le Soleil, ce qui a constitu\u00e9 une r\u00e9volution dans le domaine et a permis \u00e0 ses techniques d\u2019\u00eatre utilis\u00e9es par des astronomes du monde entier.<\/p>\n\n\n\n
Ces d\u00e9couvertes font progresser l\u2019objectif ultime de la recherche sur les exoplan\u00e8tes, \u00e0 savoir la d\u00e9couverte de signes de vie au\u2011del\u00e0 du syst\u00e8me solaire. Gr\u00e2ce aux travaux importants de M.\u00a0Doyon, il est d\u00e9sormais possible d\u2019utiliser la spectroscopie du signal d\u2019une plan\u00e8te pour d\u00e9terminer la composition chimique de son atmosph\u00e8re dans la recherche d\u2019eau, d\u2019oxyg\u00e8ne et de m\u00e9thane, par exemple.<\/p>\n\n\n\n
Les contributions essentielles de M.\u00a0Doyon visent \u00e0 faire progresser notre connaissance des exoplan\u00e8tes, ouvrant ainsi une nouvelle \u00e8re dans notre exploration et notre compr\u00e9hension de l\u2019univers.<\/p>\n","protected":false},"excerpt":{"rendered":"
