A dedicated mission to investigate exoplanetary atmospheres represents a major milestone in our quest to understand our place in the universe by placing our Solar System in context…
Transiting exoplanets from the CoRoT space mission - XIX. CoRoT-23b: a dense hot Jupiter on an eccentric orbit
D. Rouan, H. Parviainen, C. Moutou +40
We report the detection of CoRoT-23b, a hot Jupiter transiting in front of its host star with a period of 3.6314 \pm 0.0001 days. This planet was discovered thanks to photometric d…
The HARPS search for southern extra-solar planets XXXI. The M-dwarf sample
X. Bonfils, X. Delfosse, S. Udry +11
(Abridged) Searching for planets around stars with different masses probes the outcome of planetary formation for different initial conditions. This drives observations of a sample…
Planetary transit candidates in the CoRoT LRa01 field
L. Carone, D. Gandolfi, J. Cabrera +70
Context: CoRoT is a pioneering space mission whose primary goals are stellar seismology and extrasolar planets search. Its surveys of large stellar fields generate numerous planeta…
Improved precision on the radius of the nearby super-Earth 55 Cnc e
M. Gillon, B. -O. Demory, B. Benneke +9
We report on new transit photometry for the super-Earth 55 Cnc e obtained with Warm Spitzer/IRAC at 4.5 microns. An individual analysis of these new data leads to a planet radius o…
The HARPS search for southern extra-solar planets XXXII. Only 4 planets in the Gl~581 system
T. Forveille, X. Bonfils, X. Delfosse +14
The Gl 581 planetary system has generated wide interest, because its 4 planets include both the lowest mass planet known around a main sequence star other than the Sun and the firs…
The HARPS search for southern extra-solar planets XXXIV. Occurrence, mass distribution and orbital properties of super-Earths and Neptune-mass planets
M. Mayor, M. Marmier, C. Lovis +11
We report on the results of an 8-year survey carried out at the La Silla Observatory with the HARPS spectrograph to detect and characterize planets in the super-Earth and Neptune m…
The HARPS search for Earth-like planets in the habitable zone: I -- Very low-mass planets around HD20794, HD85512 and HD192310
F. Pepe, C. Lovis, D. Ségransan +7
In 2009 we started an intense radial-velocity monitoring of a few nearby, slowly-rotating and quiet solar-type stars within the dedicated HARPS-Upgrade GTO program. The goal of thi…
The HARPS search for southern extra-solar planets. XXX. Planetary systems around stars with solar-like magnetic cycles and short-term activity variation
X. Dumusque, C. Lovis, D. Ségransan +10
We present the discovery of four new long-period planets within the HARPS high-precision sample: \object{HD137388}b ( = 0.22 ), \object{HD204941}b ( = 0.27…
Transiting exoplanets from the CoRoT space mission XVII. The hot Jupiter CoRoT-17b: a very old planet
Sz. Csizmadia, C. Moutou, M. Deleuil +49
We report on the discovery of a hot Jupiter-type exoplanet, CoRoT-17b, detected by the CoRoT satellite. It has a mass of \Mjup and a radius of \Rjup, whil…
Stellar Variability of the Exoplanet Hosting Star HD 63454
Stephen R. Kane, Diana Dragomir, David R. Ciardi +9
Of the hundreds of exoplanets discovered using the radial velocity technique, many are orbiting close to their host stars with periods less than 10 days. One of these, HD 63454, is…
Spin-orbit inclinations of the exoplanetary systems HAT-P-8, HAT-P-9, HAT-P-16 and HAT-P-23
Claire Moutou, Rodrigo F. Diaz, Stephane Udry +22
We report the measurement of the spin-orbit angle of the extra-solar planets HAT-P-8 b, HAT-P-9 b, HAT-P-16 b and HAT-P-23 b, thanks to spectroscopic observations performed at the…
Detection of a transit of the super-Earth 55 Cnc e with Warm Spitzer
B. -O. Demory, M. Gillon, D. Deming +12
We report on the detection of a transit of the super-Earth 55 Cnc e with warm Spitzer in IRAC's 4.5-micron band. Our MCMC analysis includes an extensive modeling of the systematic…
WASP-23b: a transiting hot Jupiter around a K dwarf and its Rossiter-McLaughlin effect
Amaury H. M. J. Triaud, Didier Queloz, Coel Hellier +17
We report the discovery of a new transiting planet in the Southern Hemisphere. It has been found by the WASP-south transit survey and confirmed photometrically and spectroscopicall…
HD 5388 b is a 69 M_Jup companion instead of a planet
Johannes Sahlmann, Christophe Lovis, Didier Queloz +1
We examined six exoplanet host stars with non-standard Hipparcos astrometric solution, which may be indicative of unrecognised orbital motion. Using Hipparcos intermediate astromet…
