    TOI-519 b: A short-period substellar object around an M dwarf validated using multicolour photometry and phase curve analysis

    Published 2021
    “…The companion radius estimate combined with the Teff and mass limits suggests that the companion is more likely a planet than a brown dwarf, but a brown-dwarf scenario is a priori more likely given the lack of known massive planets in ≈ 1 day orbits around M dwarfs with Teff < 3800 K, and given the existence of some (but few) brown dwarfs.…”
