Substellar Objects in Nearby Young Clusters (SONYC): The bottom of the Initial Mass Function in NGC1333
Alexander Scholz, Vincent Geers, Ray Jayawardhana +4
SONYC -- Substellar Objects in Nearby Young Clusters -- is a survey program to investigate the frequency and properties of substellar objects with masses down to a few times that o…
HST/NICMOS detection of HR 8799 b in 1998
David Lafrenière, Christian Marois, René Doyon +1
Three planets have been directly imaged around the young star HR 8799. The planets are 5-13 Mjup and orbit the star at projected separations of 24-68 AU. While the initial detectio…
Direct Imaging of Multiple Planets Orbiting the Star HR 8799
C. Marois, B. Macintosh, T. Barman +5
Direct imaging of exoplanetary systems is a powerful technique that can reveal Jupiter-like planets in wide orbits, can enable detailed characterization of planetary atmospheres, a…
Direct Imaging and Spectroscopy of a Planetary Mass Candidate Companion to a Young Solar Analog
David Lafrenière, Ray Jayawardhana, Marten H. van Kerkwijk
We present Gemini near-infrared adaptive optics imaging and spectroscopy of a planetary mass candidate companion to 1RXS J160929.1-210524, a roughly solar-mass member of the 5 Myr-…
SIMP: A Near-Infrared Proper Motion Survey
Etienne Artigau, David Lafreniere, Rene Doyon +3
SIMP is a proper motion (PM) survey made with the Observatoire du Mont Megantic (OMM) wide-field near-infrared camera CPAPIR at the CTIO 1.5 m and OMM 1.6 m telescopes. The SIMP ob…
Discovery of a Wide Substellar Companion to a Nearby Low-Mass Star
Jacqueline Radigan, David Lafrenière, Ray Jayawardhana +1
We report the discovery of a wide (135+/-25 AU), unusually blue L5 companion 2MASS J17114559+4028578 to the nearby M4.5 dwarf G 203-50 as a result of a targeted search for common p…
