11 Oct 2011 | | Abstract: | Context: CoRoT is a pioneering space mission whose primary goals are stellar
seismology and extrasolar planets search. Its surveys of large stellar fields
generate numerous planetary candidates whose lightcurves have transit-like
features. An extensive analytical and observational follow-up effort is
undertaken to classify these candidates. Aims: The list of planetary transit
candidates from the CoRoT LRa01 star field in the Monoceros constellation
towards the Galactic anti-center is presented. The CoRoT observations of LRa01
lasted from 24 October 2007 to 3 March 2008. Methods: 7470 chromatic and 3938
monochromatic lightcurves were acquired and analysed. Instrumental noise and
stellar variability were treated with several filtering tools by different
teams from the CoRoT community. Different transit search algorithms were
applied to the lightcurves. Results: Fifty-one stars were classified as
planetary transit candidates in LRa01. Thirty-seven (i.e., 73 % of all
candidates) are "good" planetary candidates based on photometric analysis only.
Thirty-two (i.e., 87 % of the "good" candidates) have been followed-up. At the
time of this writing twenty-two cases have been solved and five planets have
been discovered: three transiting hot-Jupiters (CoRoT-5b, CoRoT-12b, and
CoRoT-21b), the first terrestrial transiting planet (CoRoT-7b), and another
planet in the same system (CoRoT-7c, detected by radial velocity survey only).
Evidences of another non-transiting planet in the CoRoT-7 system, namely
CoRoT-7d, have been recently found. | | Source: | arXiv, 1110.2384 | | Services: | Forum | Review | PDF | Favorites | |
