The ultracool eld dwarfs luminosity function from the Canada-France Brown Dwarf Survey
C. Reyle, P. Delorme, X. Delfosse +4
The Canada-France Brown Dwarf Survey is a wide eld survey for cool brown dwarfs conducted with the MegaCam camera on the CFHT telescope. Our objectives are to nd ultracool brown dw…
On the Age of the Widest Very Low Mass Binary
Etienne Artigau, David Lafreniere, Loic Albert +1
We have recently identified the widest very low-mass binary (2M0126AB), consisting of an M6.5V and an M8V dwarf with a separation of ~5100 AU, which is twice as large as that of th…
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…
Large-scale magnetic topologies of early M dwarfs
JF Donati, J Morin, P Petit +12
We present here additional results of a spectropolarimetric survey of a small sample of stars ranging from spectral type M0 to M8 aimed at investigating observationally how dynamo…
Large-scale magnetic topologies of mid-M dwarfs
J. Morin, J. -F. Donati, P. Petit +13
We present in this paper the first results of a spectropolarimetric analysis of a small sample (~ 20) of active stars ranging from spectral type M0 to M8, which are either fully-co…
Early spectroscopic identification of SN 2008D
D. Malesani, J. P. U. Fynbo, J. Hjorth +27
SN 2008D was discovered while following up an unusually bright X-ray transient in the nearby spiral galaxy NGC 2770. We present early optical spectra (obtained 1.75 days after the…
Finding ultracool brown dwarfs with MegaCam on CFHT: method and first results
Philippe Delorme, Chris J. Willott, Thierry Forveille +9
We present the first results of a wide field survey for cool brown dwarfs with the MegaCam camera on the CFHT telescope, the Canada-France Brown Dwarf Survey, hereafter CFBDS. Our…
HN Peg B: A Test of Models of the L to T Dwarf Transition
S. K. Leggett, D. Saumon, Loic Albert +7
Luhman and collaborators recently discovered an early-T dwarf companion to the G0 dwarf star HN Peg, using Spitzer Infrared Array Camera (IRAC) images. Companionship was establishe…
CFBDS J005910.90-011401.3: reaching the T-Y Brown Dwarf transition?
Philippe Delorme, Xavier Delfosse, Loic Albert +9
We report the discovery of CFBDS J005910.90-011401.3 (hereafter CFBDS0059), the coolest brown dwarf identified to date. We found CFBDS0059 using i' and z' images from the Canada-Fr…
