High resolution imaging of young M-type stars of the solar neighborhood: Probing the existence of companions down to the mass of Jupiter
P. Delorme, A. M. Lagrange, G. Chauvin +5
Context. High contrast imaging is a powerful technique to search for gas giant planets and brown dwarfs orbiting at separation larger than several AU. Around solar-type stars, gian…
Transmission spectrum of Venus as a transiting exoplanet
David Ehrenreich, Alfred Vidal-Madjar, Thomas Widemann +6
On 5-6 June 2012, Venus will be transiting the Sun for the last time before 2117. This event is an unique opportunity to assess the feasibility of the atmospheric characterisation…
The SOPHIE search for northern extrasolar planets. IV. Massive companions in the planet-brown dwarf boundary
R. F. Díaz, A. Santerne, J. Sahlmann +20
The mass domain where massive extrasolar planets and brown dwarfs lay is still poorly understood. Indeed, not even a clear dividing line between massive planets and brown dwarfs ha…
Corrigendum to "The upper atmosphere of the exoplanet HD209458b revealed by the sodium D lines: Temperature-pressure profile, ionization layer and thermosphere" [2011, A&A, 527, A110]
A. Vidal-Madjar, C. M. Huitson, A. Lecavelier des Etangs +7
An error was detected in the code used for the analysis of the HD209458b sodium profile (Vidal-Madjar et al. 2011). Here we present an updated T-P profile and briefly discuss the c…
SOPHIE velocimetry of Kepler transit candidates III. KOI-423b: an 18 Mjup transiting companion around an F7IV star
F. Bouchy, A. S. Bonomo, A. Santerne +10
We report the strategy and results of our radial velocity follow-up campaign with the SOPHIE spectrograph (1.93-m OHP) of four transiting planetary candidates discovered by the Kep…
Sparse aperture masking at the VLT I. Faint companion detection limits for the two debris disk stars HD 92945 and HD 141569
S. Lacour, P. Tuthill, P. Amico +4
Observational data on companion statistics around young stellar systems is needed to flesh out the formation pathways for extrasolar planets and brown dwarfs. Aperture masking is a…
