Detection and characterisation of 54 massive companions with the SOPHIE spectrograph Seven new brown dwarfs and constraints on the brown dwarf desert

Mostrar otras versiones (1)

Brown dwarfs (BD) are substellar objects intermediate between planets and stars with masses of ∼13–80 MJ . While isolated BDs are most likely produced by gravitational collapse in molecular clouds down to masses of a few MJ , a non-negligible fraction of low-mass companions might be formed throu...
