Revisiting physical parameters of the benchmark brown dwarf LHS 6343 C through a HST/WFC3 secondary eclipse observation
William Frost, Loïc Albert, René Doyon +7
The LHS 6343 system consists of a resolved M-dwarf binary with an evolved, negligibly irradiated brown dwarf, LHS 6343 C, orbiting the primary star. Such brown dwarf eclipsing bina…
CFBDSIR 2149-0403: young isolated planetary-mass object or high-metallicity low-mass brown dwarf??
P. Delorme, T. Dupuy, J. Gagné +12
We conducted a multi-wavelength, multi-instrument observational characterisation of the candidate free-floating planet CFBDSIR~J214947.2-040308.9, a late T-dwarf with possible low-…
CFBDS J111807-064016: A new L/T transition brown dwarf in a binary system
C. Reylé, P. Delorme, É. Artigau +7
Stellar-substellar binary systems are quite rare, and provide interesting benchmarks. They constrain the complex physics of substellar atmospheres, because several physical paramet…
CFBDSIR2149-0403: a 4-7 Jupiter-mass free-floating planet in the young moving group AB Doradus ?
P. Delorme, J. Gagné, L. Malo +7
Using the CFBDSIR wide field survey for brown dwarfs, we identified CFBDSIRJ214947.2-040308.9, a late T dwarf with atypically red J-Ks colour. We obtained an X-Shooter spectra, wit…
Spitzer Mid-Infrared Photometry of 500 - 750 K Brown Dwarfs
S. K. Leggett, L. Albert, E. Artigau +11
Mid-infrared data, including Spitzer warm-IRAC [3.6] and [4.5] photometry, is critical for understanding the cold population of brown dwarfs now being found, objects which have mor…
Exploring the magnetic topologies of cool stars
J. Morin, J. -F. Donati, P. Petit +19
Magnetic fields of cool stars can be directly investigated through the study of the Zeeman effect on photospheric spectral lines using several approaches. With spectroscopic measur…
The ultracool-field dwarf luminosity-function and space density from the Canada-France Brown Dwarf Survey
C. Reyle, P. Delorme, C. J. Willott +7
Context. Thanks to recent and ongoing large scale surveys, hundreds of brown dwarfs have been discovered in the last decade. The Canada-France Brown Dwarf Survey is a wide-field su…
