BANYAN. X. Discovery of a wide, low-gravity L-type companion to a fast-rotating M3 dwarf
Marie-Eve Desrochers, Etienne Artigau, Jonathan Gagné +4
We report the discovery of a substellar-mass co-moving companion to 2MASS J22501512+2325342, an M3 candidate member of the young (130--200 Myr) AB Doradus Moving Group (ABDMG). Thi…
PSYM-WIDE: a survey for large-separation planetary-mass companions to late spectral type members of young moving groups
Marie-Eve Naud, Étienne Artigau, René Doyon +5
We present the results of a direct-imaging survey for very large separation (100 au), companions around 95 nearby young K5-L5 stars and brown dwarfs. They are high-likelihood ca…
Characterizing 51 Eri b from 1-5 m: a partly-cloudy exoplanet
Abhijith Rajan, Julien Rameau, Robert J. De Rosa +58
We present spectro-photometry spanning 1-5 m of 51 Eridani b, a 2-10 M planet discovered by the Gemini Planet Imager Exoplanet Survey. In this study, we present new…
SIMP J013656.5+093347 is Likely a Planetary-Mass Object in the Carina-Near Moving Group
Jonathan Gagné, Jacqueline K. Faherty, Adam J. Burgasser +6
We report the discovery that the nearby ( 6 pc) photometrically variable T2.5 dwarf SIMP~J013656.5+093347 is a likely member of the 200 Myr-old Carina-Near moving grou…
An Optical/near-infrared investigation of HD 100546 b with the Gemini Planet Imager and MagAO
Julien Rameau, Katherine B. Follette, Laurent Pueyo +52
We present H band spectroscopic and Halpha photometric observations of HD 100546 obtained with GPI and MagAO. We detect H band emission at the location of the protoplanet HD 100546…
Mid-infrared characterization of the planetary-mass companion ROXs 42B b
Sebastian Daemgen, Kamen Todorov, Jasmin Silva +10
We present new Keck/NIRC2 35 m infrared photometry of the planetary-mass companion to ROXS 42B in , and for the first time in Brackett- (Br) and in $M_\mathrm…
