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-…

Follow-up and characterization of the TESS exoplanets with SOPHIE, SPIRou, and JWST

N. Crouzet, X. Bonfils, X. Delfosse +12

The NASA TESS mission will deliver hundreds of transiting exoplanet candidates orbiting bright stars. The spectrometers SOPHIE at OHP and SPIRou at CFHT will be ideal to obtain rad…

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…

The stable magnetic field of the fullly-convective star V374 Peg

J. Morin, J. -F. Donati, T. Forveille +10

We report in this paper phase-resolved spectropolarimetric observations of the rapidly-rotating fully-convective M4 dwarf V374 Peg, on which a strong, mainly axisymmetric, large-sc…
