Ground based radial velocity (RV) searches continue to discover exoplanets below Neptune mass down to Earth mass. Furthermore, ground based transit searches now reach milli-mag photometric precision and can discover Neptune size planets around bright stars. These searches will find exoplanets around bright stars anywhere on the sky, their discoveries representing prime science targets for further study due to the proximity and brightness of their host stars. A mission for transit follow-up…

Searching for transits in the WTS with difference imaging light curves
The Wide Field Camera Transit Survey is a pioneer program aimed to search for extra-solar planets in the near-infrared. The standard data reduction pipeline of the program uses aperture photometry to
Ground-based photometry of the 21-day Neptune HD106315c
Space-based transit surveys such as K2 and TESS allow the detection of small transiting planets with orbital periods beyond 10 days. Few of these warm Neptunes are currently known around stars bright
Long-period exoplanets from photometric transit surveys
The Bayesian transit-fitting tool ("Namaste: An MCMC Analysis of Single Transit Exoplanets") was developed to extract planetary and orbital information from single transits, and was applied to 71 candidate events detected in K2 photometry, which helped to characterise large numbers of long period planets in this way.

Continuous data releases throughout the Transiting Exoplanet Survey Satellite (TESS) primary mission will provide unique opportunities for the exoplanet community at large to contribute to maximizing
The SOPHIE search for northern extrasolar planets VII. A warm Neptune orbiting HD164595
High-precision radial velocity surveys explore the population of low-mass exoplanets orbiting bright stars. This allows accurately deriving their orbital parameters such as their occurrence rate and
The bright star survey telescope for the planetary transit survey in Antarctica
Transiting extrasolar planets (exoplanets), especially those orbiting bright stars, are desired for study of the diversity of planetary compositions, internal structures and atmospheres beyond our
CHEOPS observations of the HD 108236 planetary system: a fifth planet, improved ephemerides, and planetary radii
Context. The detection of a super-Earth and three mini-Neptunes transiting the bright (V = 9.2 mag) star HD 108236 (also known as TOI-1233) was recently reported on the basis of TESS and ground-based
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
K2-111 b − a short period super-Earth transiting a metal poor, evolved old star
Context. From a light curve acquired through the K2 space mission, the star K2-111(EPIC 210894022) has been identified as possibly orbited by a transiting planet. Aims: Our aim is to confirm the
Age consistency between exoplanet hosts and field stars
Transiting planets around stars are discovered mostly through photometric surveys. Unlike radial velocity surveys, photometric surveys do not tend to target slow rotators, inactive or metal-rich


Kepler Planet-Detection Mission: Introduction and First Results
The planetary findings derived from the first six weeks of observations with the Kepler mission are summarized, which include the detection of five new exoplanets, which confirm the existence of planets with densities substantially lower than those predicted for gas giant planets.
We have detected transits of the innermost planet “e” orbiting 55 Cnc (V = 6.0), based on two weeks of nearly continuous photometric monitoring with the MOST space telescope. The transits occur with
The changing phases of extrasolar planet CoRoT-1b
Optical photometric data obtained over 36 planetary orbits of the transiting hot Jupiter CoRoT-1b are consistent with the nightside hemisphere of the planet being entirely black, with the dayside flux dominating the optical phase curve.
On the Method to Infer an Atmosphere on a Tidally Locked Super Earth Exoplanet and Upper Limits to GJ 876d
We develop a method to infer or rule out the presence of an atmosphere on a tidally locked hot super Earth. The question of atmosphere retention is a fundamental one, especially for planets orbiting
We report on the detection of infrared light from the super-Earth 55 Cnc e, based on four occultations obtained with Warm Spitzer at 4.5 μm. Our data analysis consists of a two-part process. In a
Extrasolar planets: Water on distant worlds
The first convincing detection of water vapour in the atmosphere of a gas-giant planet from outside the authors' Solar System indicates that the answer is yes.
