BANYAN. V. A Systematic All-Sky Survey for New Very Late-Type Low-Mass Stars and Brown Dwarfs in Nearby Young Moving Groups
Jonathan Gagné, David Lafrenière, René Doyon +2
We present the BANYAN All-Sky Survey (BASS) catalog, consisting of 228 new late-type (M4-L6) candidate members of nearby young moving groups (YMGs) with an expected false-positive…
Results from BASS, the BANYAN All-Sky Survey
Jonathan Gagné, David Lafrenière, René Doyon +3
We present results from the BANYAN All-Sky Survey (BASS), a systematic all-sky survey for brown dwarf candidates in young moving groups. We describe a cross-match of the 2MASS and…
GRACES: Gemini remote access to CFHT ESPaDOnS Spectrograph through the longest astronomical fiber ever made (Experimental phase completed.)
André-Nicolas Chené, John Pazder, Gregory Barrick +17
The Gemini Remote Access to CFHT ESPaDONS Spectrograph has achieved first light of its experimental phase in May 2014. It successfully collected light from the Gemini North telesco…
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…
Telluric-line subtraction in high-accuracy velocimetry: a PCA-based approach
Étienne Artigau, Nicola Astudillo-Defru, Xavier Delfosse +8
Optical velocimetry has led to the detection of more than 500 planets to date and there is a strong effort to push m/s velocimetry to the near-infrared to access cooler and lighter…
BANYAN. IV. Fundamental parameters of low-mass star candidates in nearby young stellar kinematic groups - Isochronal Age determination using Magnetic evolutionary models
Lison Malo, René Doyon, Gregory A. Feiden +5
Based on high resolution optical spectra obtained with ESPaDOnS at CFHT, we determine fundamental parameters (\Teff, R, \Lbol, \logg\ and metallicity) for 59 candidate members of n…
