The First High-Contrast Images of X-Ray Binaries: Detection of Candidate Companions in the Cas Analog RX J1744.72713
M. Prasow-Émond, J. Hlavacek-Larrondo, K. Fogarty +16
X-ray binaries provide exceptional laboratories for understanding the physics of matter under the most extreme conditions. Until recently, there were few, if any, observational con…
Constraints on the occurrence and distribution of 1--20 \mj\ companions to stars at separations of 5--5000\,au from a compilation of direct imaging surveys
Frédérique Baron, David Lafrenière, Étienne Artigau +4
We present the first statistical analysis of exoplanet direct imaging surveys combining adaptive optics imaging at small separations with deep seeing-limited observations at large…
WEIRD: Wide-orbit Exoplanet search with InfraRed Direct imaging
Frédérique Baron, Étienne Artigau, Julien Rameau +9
We report results from the Wide-orbit Exoplanet search with InfraRed Direct imaging (WEIRD), a survey designed to search for Jupiter-like companions on very wide orbits (1000 to 50…
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…
A search for photometric variability in the young T3.5 planetary-mass companion GU Psc b
Marie-Eve Naud, Étienne Artigau, Jason F. Rowe +5
We present a photometric -band variability study of GU Psc b, a T3.5 co-moving planetary-mass companion (9-13) to a young (150 Myr) M3 member of the AB Dorad…
CFBDSIR 2149-0403: young isolated planetary-mass object or high-metallicity low-mass brown dwarf??
P. Delorme, T. Dupuy, J. Gagné +12
We conducted a multi-wavelength, multi-instrument observational characterisation of the candidate free-floating planet CFBDSIR~J214947.2-040308.9, a late T-dwarf with possible low-…
BANYAN. VII. A New Population of Young Substellar Candidate Members of Nearby Moving Groups from the BASS Survey
Jonathan Gagné, Jacqueline K. Faherty, Kelle L. Cruz +9
[Abbreviated] We present the results of a near-infrared (NIR) spectroscopic follow-up survey of 182 M4-L7 low-mass stars and brown dwarfs (BDs) from the BANYAN All-Sky Survey (BASS…
The BANYAN All-Sky Survey for Brown Dwarf Members of Young Moving Groups
Jonathan Gagné, David Lafrenière, René Doyon +9
We describe in this work the BASS survey for brown dwarfs in young moving groups of the solar neighborhood, and summarize the results that it generated. These include the discovery…
BANYAN. VI. Discovery of a companion at the brown dwarf/planet-mass limit to a Tucana-Horologium M dwarf
Étienne Artigau, Jonathan Gagné, Jacqueline Faherty +5
We report the discovery of a substellar companion to 2MASS J02192210-3925225, a young M6 candidate member of the Tucana-Horologium association (30 - 40 Myr). This L4 compan…
Discovery of a wide planetary-mass companion to the young M3 star GU Psc
Marie-Eve Naud, Étienne Artigau, Lison Malo +11
We present the discovery of a co-moving planetary-mass companion ~42" (~2000 AU) from a young M3 star, GU Psc, likely member of the young AB Doradus Moving Group (ABDMG). The compa…
Direct imaging discovery of 12-14 Jupiter mass object orbiting a young binary system of very low-mass stars
P. Delorme, J. Gagné, J. H. Girard +8
Context. Though only a handful of extrasolar planets have been discovered via direct imaging, each of these discoveries had tremendous impact on our understanding of planetary form…
