The Gemini Planet Imager Exoplanet Survey: Dynamical Mass of the Exoplanet beta Pictoris b from Combined Direct Imaging and Astrometry

Eric L. Nielsen, Robert J. De Rosa, Jason J. Wang +51

We present new observations of the planet beta Pictoris b from 2018 with GPI, the first GPI observations following conjunction. Based on these new measurements, we perform a joint…

The detection and characterisation of 54 massive companions with the SOPHIE spectrograph -- 7 new brown dwarfs and constraints on the BD desert

F. Kiefer, G. Hébrard, J. Sahlmann +35

Brown-dwarfs are substellar objects with masses intermediate between planets and stars within about 13-80Mjup. While isolated BDs are most likely produced by gravitational collapse…

The Ultracool SpeXtroscopic Survey. I. Volume-Limited Spectroscopic Sample and Luminosity Function of M7L5 Ultracool Dwarfs

Daniella C. Bardalez Gagliuffi, Adam J. Burgasser, Sarah J. Schmidt +9

We present a volume-limited, spectroscopically-verified sample of M7L5 ultracool dwarfs within 25\,pc. The sample contains 410 sources, of which have trigonometric distan…

Wide-Orbit Exoplanet Demographics

David P. Bennett, Rachel Akeson, Yann Alibert +41

The Kepler, K2 and TESS transit surveys are revolutionizing our understanding of planets orbiting close to their host stars and our understanding of exoplanet systems in general, b…

Substellar Multiplicity Throughout the Ages

Daniella Bardalez Gagliuffi, Kimberly Ward-Duong, Jacqueline Faherty +11

Substellar multiplicity is a key outcome of the formation process. The biggest challenge for the next decade will be to distinguish between the formation history, environmental con…
