A cool starspot or a second transiting planet in the TrES-1 system?
M. Rabus, R. Alonso, J. A. Belmonte +6
We investigate the origin of a flux increase found during a transit of TrES-1, observed with the HST. This feature in the HST light curve cannot be attributed to noise and is suppo…
Transiting exoplanets from the CoRoT space mission VI. CoRoT-Exo-3b: The first secure inhabitant of the brown-dwarf desert
M. Deleuil, H. J. Deeg, R. Alonso +2
Context. The CoRoT space mission routinely provides high-precision photometric measurements of thousands of stars that have been continuously observed for months. Aims. The discove…
Transiting exoplanets from the CoRoT space mission IV: CoRoT-Exo-4b: A transiting planet in a 9.2 day synchronous orbit
S. Aigrain, A. Collier Cameron, M. Ollivier +32
CoRoT, the first space-based transit search, provides ultra-high precision light curves with continuous time-sampling over periods, of up to 5 months. This allows the detection of…
Transiting exoplanets from the CoRoT space mission I - CoRoT-Exo-1b: a low-density short-period planet around a G0V star
P. Barge, A. Baglin, M. Auvergne +35
Context. The pioneer space mission for photometric planet searches, CoRoT, steadily monitors about 12,000 stars in each of its fields of view; it is able to detect transit candidat…
HD 17156b: A Transiting Planet with a 21.2 Day Period and an Eccentric Orbit
M. Barbieri, R. Alonso, G. Laughlin +8
We report the detection of transits by the 3.1 M_Jup companion to the V=8.17 G0V star HD 17156. The transit was observed by three independant observers on Sept. 9/10, 2007 (two in…
Detecting false alarms in transit data from space: Rejection methods tested in Corot Blind Test 2
J. M. Almenara, H. J. Deeg, C. Regulo +1
Transit searches provide a large number of planet candidates. Before attempting follow-up observations, the best effort should be spent in classifying the light-curves, rejecting f…
