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 data secured with the CoRoT satellite, combined with spectroscopic radial velocity (RV) measurements. A photometric search for possible background eclipsing binaries conducted at CFHT and OGS concluded with a very low risk of false positives. The usual techniques of combining RV and transit data simultaneously were… Expand

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 toExpand

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.

WASP-12b: The hottest transiting extrasolar planet yet discovered
TLDR
The planet has an equilibrium temperature of T eq = 2516 K caused by its very short period orbit around the hot, twelfth magnitude host star and has the largest radius of any transiting planet yet detected. Expand
A transiting giant planet with a temperature between 250 K and 430 K
TLDR
Transit observations of CoRoT-9b, the largest of all transiting planets, are reported, which is found to be well described by standard evolution models with an inferred interior composition consistent with that of Jupiter and Saturn. Expand
