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…
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 the Widest Very Low Mass Binary
Étienne Artigau, David Lafrenière, René Doyon +3
We report the discovery of a very low mass binary system (primary mass <0.1 Msol) with a projected separation of ~5100 AU, more than twice that of the widest previously known syste…
Discovery of the brightest T dwarf in the northern hemisphere
Etienne Artigau, Rene Doyon, David Lafreniere +3
We report the discovery of a bright (H=12.77) brown dwarf designated SIMP J013656.5+093347. The discovery was made as part of a near-infrared proper motion survey, SIMP (Sondage In…
