Context. Observations of transiting extrasolar planets are of key importance to our understanding of planets because their mass, radius, and mass density can be determined. These measurements indicate that planets of similar mass can have very di erent radii. For low-density planets, it is generally assumed that they are inflated owing to their proximity to the host-star. To determine the causes of this inflation, it is necessary to obtain a statistically significant sample of planets with… Expand

Planets, candidates, and binaries from the CoRoT/Exoplanet programme. The CoRoT transit catalogue
The CoRoT space mission observed 163 665 stars over 26 stellar fields in the faint star channel. The exoplanet teams detected a total of 4123 transit-like features in the 177 454 light curves. WeExpand
Discrepancies between isochrone fitting and gyrochronology for exoplanet host stars
Using a sample of 68 planet-hosting stars, I carry out a comparison of isochrone fitting and gyrochronology to investigate whether tidal interactions between the stars and their planets are leadingExpand
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
We study the production of hot Jupiters (HJs) in stellar binaries. We show that the “eccentric Kozai–Lidov” (EKL) mechanism can play a key role in the dynamical evolution of a star–planet–star tripleExpand
