Aims. We report the discovery of a massive and dense transiting planet CoRoT-27b on a 3.58 day orbit around a 4.2 Gyr-old G2 star. The planet candidate was identified from the CoRoT photometry, and was confirmed as a planet with ground-based spectroscopy. Methods. The confirmation of the planet candidate is based on radial velocity observations combined with imaging to rule out blends. The characterisation of the planet and its host star is carried out using a Bayesian approach where all the… 
Transiting exoplanets from the CoRoT space mission XXVIII. CoRoT-33b, an object in the brown dwarf desert with 2:3 commensurability with its host star
We report the detection of a rare transiting brown dwarf with a mass of 59 M_Jup and radius of 1.1 R_Jup around the metal-rich, [Fe/H] = +0.44, G9V star CoRoT-33. The orbit is eccentric (e = 0.07)
CoRoT : a first space-based transiting survey to explore the close-in planets populations
The CoRoT (COnvection, internal ROtation and Transiting planets) space mission was launched in the last days of 2006, becoming the first major space mission dedicated to the search for and study of
CoRoT: The first space-based transit survey to explore the close-in planet population
The CoRoT (COnvection, internal ROtation and Transiting planets) space mission was launched in the last days of 2006, becoming the first major space mission dedicated to the search for and study of
SOPHIE velocimetry of Kepler transit candidates XIII. KOI-189 b and KOI-686 b: two very low-mass stars in long-period orbits
We present the radial-velocity follow-up of two Kepler planetary transiting candidates (KOI-189 and KOI-686) carried out with the SOPHIE spectrograph at the Observatoire de Haute Provence. These data
HATS-70b: A 13 MJ Brown Dwarf Transiting an A Star
We report the discovery of HATS-70b, a transiting brown dwarf at the deuterium burning limit. HATS-70b has a mass of and a radius of , residing in a close-in orbit with a period of days. The host
The SOPHIE search for northern extrasolar planets - IX. Populating the brown dwarf desert
Radial velocity planet search surveys of nearby solar-type stars have shown a strong scarcity of brown dwarf companions within similar to 5 AU. There is presently no comprehensive explanation for
Stellar Obliquity and Magnetic Activity of Planet-hosting Stars and Eclipsing Binaries Based on Transit Chord Correlation
The light curve of an eclipsing system shows anomalies whenever the eclipsing body passes in front of active regions on the eclipsed star. In some cases, the pattern of anomalies can be used to
HATS-22b, HATS-23b and HATS-24b: three new transiting super-Jupiters from the HATSouth project
We report the discovery of three moderately high-mass transiting hot Jupiters from the HATSouth survey: HATS-22b, HATS-23b and HATS-24b. These planets add to the number of known planets in the
TOI 694b and TIC 220568520b: Two Low-mass Companions near the Hydrogen-burning Mass Limit Orbiting Sun-like Stars
We report the discovery of TOI 694 b and TIC 220568520 b, two low-mass stellar companions in eccentric orbits around metal-rich Sun-like stars, first detected by the Transiting Exoplanet Survey
We present the results of a near-infrared (NIR) spectroscopic follow-up survey of 182 M4–L7 low-mass stars and brown dwarfs (BDs) from the BANYAN All-Sky Survey (BASS) for candidate members of


Structure and evolution of the first CoRoT exoplanets: probing the brown dwarf/planet overlapping mass regime
We present detailed structure and evolution calculations for the first transiting extrasolar planets discovered by the space-based CoRoT mission. Comparisons between theoretical and observed radii
We present the discovery of a hot Jupiter transiting an F star in a close visual (0.″3 sky projected angular separation) binary system. The dilution of the host star's light by the nearly equal
Noise properties of the CoRoT ? data A planet-finding perspective
In this short paper, we study the photometric precision of stellar light curves obtained by the CoRoT satellite in its planet-finding channel, with a particular emphasis on the time scales
An analysis of the CoRoT-2 system: A young spotted star and its inflated giant planet
Context: CoRoT-2b is one of the most anomalously large exoplanet known. Given its large mass, its large radius cannot be explained by standard evolution models. Interestingly, the planet's parent
Ground-based photometry of space-based transit detections: photometric follow-up of the CoRoT  mission
The motivation, techniques and performance of the ground-based photometric follow-up of transit detections by the CoRoT space mission are presented. Its principal raison d’etre arises from the much
An orbital period of 0.94 days for the hot-Jupiter planet WASP-18b
Either WASP-18 is in a rare, exceptionally short-lived state, or the tidal dissipation in this system (and possibly other hot-Jupiter systems) must be much weaker than in the Solar System.
