Patrick Dufour

Patrick Dufour is a Professor at the University of Montreal specializing in white dwarf astrophysics. His research focuses on the study of white dwarf atmospheres, combining theoretical atmospheric models with observational data from spectroscopic and photometric studies. He investigates the presence of heavy elements in white dwarfs, which indicate accretion of planetary debris from tidally disrupted rocky bodies. His work provides insights into extrasolar planetary system composition and evolution. Dufour supervises graduate students like Érika Le Bourdais and has advised former student Maude Fortier-Archambault (MSc 2019). He collaborates on missions like CASTOR and uses advanced instrumentation such as JWST and HST. His research highlights unique opportunities to study exoplanetary material through polluted white dwarfs.

Key areas of expertise include stellar spectroscopy, planetary debris analysis, and machine learning applications in astrophysics. Over 100 peer-reviewed articles document his contributions, emphasizing interdisciplinary approaches to understanding planetary system formation and evolution.
