Context. 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 through the planet-formation channel in protoplanetary discs. The upper mass limit of objects formed within discs is still observationally unknown, the main reason being the strong dearth of BD… Expand
Populating the brown dwarf and stellar boundary: Five stars with transiting companions near the hydrogen-burning mass limit
We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exoplanet SurveyExpand
Determining the mass of the planetary candidate HD 114762 b using Gaia
The first planetary candidate discovered by Latham et al. (1989) with radial velocities around a solar-like star other than the Sun, HD 114762 b, was detected with a minimum mass of 11 Mjup. TheExpand
Characterizing brown dwarf companions with IRDIS long-slit spectroscopy: HD 1160 B and HD 19467 B

We present the discovery and characterization of WASP-148, a new extrasolar system that includes at least two giant planets. The host star is a slowly rotating inactive late-G dwarf with a V = 12Expand
True Masses of the Long-period Companions to HD 92987 and HD 221420 from Hipparcos–Gaia Astrometry
The extensive time span of modern radial velocity surveys has made the discovery of long-period substellar companions more common in recent years; however, measuring the true masses of these objectsExpand
