More than 200 extrasolar planets have been discovered around relatively nearby stars, primarily through the Doppler line shifts owing to reflex motions of their host stars, and more recently through transits of some planets across the faces of the host stars. The detection of planets with the shortest known periods, 1.2–2.5 days, has mainly resulted from transit surveys which have generally targeted stars more massive than 0.75 M[circdot], where M[circdot] is the mass of the Sun. Here we report… Expand

Transiting Planets in the Galactic Bulge from SWEEPS Survey and Implications
Abstract The SWEEPS (Sagittarius Window Eclipsing Extrasolar Planet Search) program was aimed at detecting planets around stars in the Galactic bulge, not only to determine their physical properties,Expand
Characterization of the stellar variability in CoRoT fields with BEST telescopes
The first extrasolar planet 51 Peg b around the G-type star has been reported in 1995. The planet with few Jupiter masses orbiting its star very closely was detected by measurement of the oscillationExpand
Extrasolar Giant Planets and X-Ray Activity
We have carried out a survey of X-ray emission from stars with giant planets, combining both archival and targeted surveys. Over 230 stars have been currently identified as possessing planets, andExpand
The Monitor project : the search for transits in the open cluster NGC 2362
We present the results of a systematic search for transiting planets in a ∼5 Myr open cluster, NGC 2362. We observed ∼1200 candidate cluster members, of which ∼475 are believed to be genuine clusterExpand
Kinematics of the SWEEPS transiting planet candidates
Abstract In 2004 a deep sequence of HST images of the Bulge was used to identify sixteen transiting extrasolar planet candidates (the SWEEPS candidates; Sahu et al. 2006), of which at least seven areExpand
Exoplanets beyond the Solar neighbourhood: Galactic tidal perturbations
The majority of Milky Way extrasolar planets likely reside within a few kpc of the Galactic centre. The Galactic tidal forces acting on planets scale inversely with radius in the Galaxy and so areExpand
Probing the Interiors of Very Hot Jupiters Using Transit Light Curves
Accurately understanding the interior structure of extrasolar planets is critical for inferring their formation and evolution. The internal density distribution of a planet has a direct effect on theExpand
SuperWASP-North extrasolar planet candidates between 3 < RA < 6
The Wide Angle Search for Planets (WASP) photometrically surveys a large number of nearby stars to uncover candidate extrasolar planet systems by virtue of small-amplitude light curve dips on a lessExpand
Measuring the Galactic Distribution of Transiting Planets with WFIRST
The WFIRST microlensing mission will measure precise light curves and relative parallaxes for millions of stars, giving it the potential to characterize short-period transiting planets all along theExpand
The imprint of X-ray photoevaporation of planet-forming discs on the orbital distribution of giant planets
High energy radiation from a planet host star can have strong influence on the final habitability of a system through several mechanisms. In this context we have constructed a catalogue containingExpand

An extrasolar planet that transits the disk of its parent star
Planets orbiting other stars could in principle be found through the periodic dimming of starlight as a planet moves across—or ‘transits’—the line of sight between the observer and the star.Expand
Discovery of a cool planet of 5.5 Earth masses through gravitational microlensing
TLDR
The detection of a cool, sub-Neptune-mass planets may be more common than gas giant planets, as predicted by the core accretion theory, and is suggested to name OGLE-2005-BLG-390Lb, indicating a planetary mass companion to the lens star of the microlensing event. Expand
Detection of Planetary Transits Across a Sun-like Star.
TLDR
High-precision, high-cadence photometric measurements of the star HD 209458 are reported, which is known from radial velocity measurements to have a planetary-mass companion in a close orbit and the detailed shape of the transit curve due to both the limb darkening of thestar and the finite size of the planet is clearly evident.

Orbital evolution and migration of giant planets: modeling extrasolar planets
Giant planets in circumstellar disks can migrate inward from their initial (formation) positions. Radial migration is caused by inward torques between the planet and the disk, by outward torquesExpand
