An international team of researchers from multiple institutions, including INRS, is shedding light on the mystery of matter accretion in young stars. Published in the November 1, 2017 Science Advances online journal, their discovery helps explain how matter accumulates on the surface of a young star and reconciles the theory behind and observations on the accretion process—a matter of debate among astrophysicists because of the limited number of theoretical models and actual observations.
