Jonathan Gagné’s
Astrophysics Research

I’m a researcher in astrophysics at the Rio Tinto Alcan planetarium and adjunct professor at Université de Montréal.

My Research Interests

I study brown dwarfs, exoplanets and young stars in our neighborhood of the Galaxy.

I also search for cold, planetary-mass objects not in orbit around a star. These objects are rare, but once we find them they become valuable to better understand the atmospheres of giant exoplanets, because they are not located right next to a bright star that blinds our instruments.

Read my astrophysics blog to learn more about my research. No need to be a scientist!

Science Papers

BANYAN Σ is for researchers to determine if a star may be part of a known stellar association

I also write about coffee brewing!
