DOI: 10.1029/2019eo127841
Abstract: Once thought to be part of the same population, planets larger than Jupiter and “failed stars” likely grow via different mechanisms, the Gemini Planet Imager Exoplanet Survey has shown. read more here.

DOI: 10.1093/mnras/stab2429
Abstract: Super-Jupiters, brown dwarfs, and stars can form from the collapse of self-gravitating discs. Such discs are turbulent, with flocculent spiral arms accelerating gas to transonic speeds horizontally and vertically. Objects that fragment from gravito-turbulent discs… read more here.

DOI: 10.1093/mnras/stad1315
Abstract: Brown dwarfs with well-measured masses, ages and luminosities provide direct benchmark tests of substellar formation and evolutionary models. We report the first results from a direct imaging survey aiming to find and characterize substellar companions… read more here.

DOI: 10.1093/mnras/stad1329
Abstract: We present results from the first molecular line survey to search for the fundamental complex organic molecule, methanol (CH3OH), in 14 Class 0/I proto-brown dwarfs (proto-BDs). IRAM 30-m observations over the frequency range of 92-116 GHz… read more here.

DOI: 10.1093/mnras/stz777
Abstract: We presented 15 new T dwarfs that were selected from UKIRT Infrared Deep Sky Survey, Visible and Infrared Survey Telescope for Astronomy , and Wide-field Infrared Survey Explorer surveys, and confirmed with optical to near-infrared spectra… read more here.
