The discovery of WASP-151b, WASP-153b, WASP-156b: Insights on giant planet migration and the upper boundary of the Neptunian desert
Olivier. D. S. Demangeon, F. Faedi, G. Hébrard +31
To investigate the origin of the features discovered in the exoplanet population, the knowledge of exoplanets' mass and radius with a good precision is essential. In this paper, we…
Detection of a repeated transit signature in the light curve of the enigma star KIC 8462852: a 928-day period?
Flavien Kiefer, Alain Lecavelier des Etangs, Alfred Vidal-Madjar +3
As revealed by its peculiar Kepler light curve, the enigmatic star KIC 8462852 undergoes short and deep flux dimmings at a priori unrelated epochs. It presents nonetheless all othe…
Precise masses for the transiting planetary system HD 106315 with HARPS
S. C. C. Barros, H. Gosselin, J. Lillo-Box +45
The multi-planetary system HD 106315 was recently found in K2 data . The planets have periods of and days, and radii of a…
Spin states of asteroids in the Eos collisional family
J. Hanuš, M. Delbo', V. Alí-Lagoa +33
Eos family was created during a catastrophic impact about 1.3 Gyr ago. Rotation states of individual family members contain information about the history of the whole population. W…
Search for rings and satellites around the exoplanet CoRoT-9b using Spitzer photometry
A. Lecavelier des Etangs, G. Hébrard, S. Blandin +9
Using Spitzer photometry at 4.5 microns, we search for rings and satellites around the long period transiting planet CoRoT-9b. We observed two transits in 2010 and 2011. From their…
A deeper view of the CoRoT-9 planetary system. A small non-zero eccentricity for CoRoT-9b likely generated by planet-planet scattering
A. S. Bonomo, G. Hébrard, S. N. Raymond +27
CoRoT-9b is one of the rare long-period (P=95.3 days) transiting giant planets with a measured mass known to date. We present a new analysis of the CoRoT-9 system based on five yea…
