Abstract:
The CoRoT mission during its flight-phase 2007-2012 delivered the
light-curves for over 2000 eclipsing binaries. Data from the Kepler
mission have proven the existence of several transiting circumbinary
planets. Albeit light-curves from CoRoT have typically lower precision
and shorter coverage, CoRoT's number of targets is similar to Kepler,
and some of the known circumbinary planets could potentially be
detected in CoRoT data as well. The aim of this work has been a
revision of the entire CoRoT data-set for the presence of circumbinary
planets, and the derivation of limits to the abundances of such
planets. We developed a code which removes the light curve of the
eclipsing binaries and searches for quasi-periodic transit-like
features in a light curve after removal of binary eclipses and
instrumental features. The code needs little information on the sample
systems and can be used for other space missions as well, like Kepler,
K2, TESS and PLATO. The code is broad in the requirements leading to
detections, but was tuned to deliver an amount of detections that is
manageable in a subsequent, mainly visual, revision about their
nature. In the CoRoT sample we identified three planet candidates
whose transits would have arisen from a single pass across the central
binary. No candidates remained however with transit events from
multiple planetary orbits. We calculated the upper limits for the
number of Jupiter, Saturn and Neptune sized planets in co-planar
orbits for different orbital period ranges. We found that there are
much less giant planets in short-periodic orbits around close binary
systems than around single stars.
