A Brown Dwarf Census from the SIMP Survey
Jasmin Robert, Jonathan Gagné, Étienne Artigau +8
We have conducted a near-infrared (NIR) proper motion survey, the Sondage Infrarouge de Mouvement Propre, in order to discover field ultracool dwarfs (UCD) in the solar neighborhoo…
Discovery And Characterization of Wide Binary Systems With a Very Low Mass Component
Frédérique Baron, David Lafrenière, Étienne Artigau +7
We report the discovery of 14 low-mass binary systems containing mid-M to mid-L dwarf companions with separations larger than 250 AU. We also report the independent discovery of 9…
SIMP J2154-1055: A New Low-Gravity L4 Brown Dwarf Candidate Member of the Argus Association
Jonathan Gagné, David Lafrenière, René Doyon +4
We present SIMP J21543454-1055308, a new L4 brown dwarf identified in the Sondage Infrarouge de Mouvement Propre (SIMP) survey that displays signs of low gravity in its near-inf…
CLOUDS search for variability in brown dwarf atmospheres
B. Goldman, M. C. Cushing, M. S. Marley +21
Context: L-type ultra-cool dwarfs and brown dwarfs have cloudy atmospheres that could host weather-like phenomena. The detection of photometric or spectral variability would provid…
The Gemini Deep Planet Survey -- GDPS
David Lafreniere, Rene Doyon, Christian Marois +10
We present the results of the Gemini Deep Planet Survey, a near-infrared adaptive optics search for giant planets and brown dwarfs around nearby young stars. The observations were…
Improving the speckle noise attenuation of simultaneous spectral differential imaging with a focal plane holographic diffuser
David Lafrenière, René Doyon, Daniel Nadeau Étienne Artigau +2
Direct exoplanet detection is limited by speckle noise in the point spread function (PSF) of the central star. This noise can be reduced by subtracting PSF images obtained simultan…
