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…
Stellar activity of planetary host star HD 189733
I. Boisse, C. Moutou, A. Vidal-Madjar +20
Extra-solar planet search programs require high-precision velocity measurements. They need to study how to disentangle radial-velocity variations due to Doppler motion from the noi…
Molecules in the disk orbiting the twin young suns of V4046 Sgr
Joel H. Kastner, B. Zuckerman, Pierre Hily-Blant +1
We report the results of a mm-wave molecular line survey of the nearby (D ~ 70 pc), 12 Myr-old system V4046 Sgr -- a tight (9 R_sun separation), short-period (2.42 day) binary with…
The HARPS search for southern extra-solar planets: XIV. Gl 176b, a super-Earth rather than a Neptune, and at a different period
T. Forveille, X. Bonfils, X. Delfosse +10
A 10.24 days Neptune-mass planet was recently announced to orbit the nearby M2 dwarf Gl 176, based on 28 radial velocities measured with the HRS spectrograph on the Hobby-Heberly T…
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…
Prospects for near-infrared characterisation of hot Jupiters with VSI
S. Renard, O. Absil, J. -P. Berger +3
In this paper, we study the feasibility of obtaining near-infrared spectra of bright extrasolar planets with the 2nd generation VLTI Spectro-Imager instrument (VSI), which has the…
