Thomas Allan Aaron Sigut (b. 1966) is a Canadian astronomer who completed his PhD at the University of Toronto on infrared Rydberg transitions in B stars in 1995. He is known for his research on circumstellar disks around hot stars, classical Be stars, Herbig Ae/Be stars and non-LTE radiative transfer as applied to precise stellar abundance determinations.

Martin Houde (b. 1963) is a Canadian astronomer studying the physical processes involved in the formation of stars. He completed his PhD in Physics at the Université de Montréal in 2001. His research spans magnetic fields and turbulence in molecular clouds, the polarization of molecular spectral lines, astronomical instrumentation and super-radiance.

Roger Cayrel (1925–2021) was a French astronomer internationally recognised as a pioneer in the study of stellar atmospheres. He has provided outstanding contributions in theoretical astrophysics, as well as in the understanding of the oldest stars and chemical evolution of the Milky Way. He was the first director of the Canada-France-Hawaii Telescope.
