Starspot activity and rotation of the planet-hosting star Kepler-17
Aldo S. Bonomo, Antonino F. Lanza
Context. Kepler-17 is a G2V sun-like star accompanied by a transiting planet with a mass of ~2.5 Jupiter masses and an orbital period of 1.486 d, recently discovered by the Kepler…
Detection of Neptune-size planetary candidates with CoRoT data. Comparison with the planet occurrence rate derived from Kepler
Aldo S. Bonomo, Pierre-Yves Chabaud, Magali Deleuil +10
[Abridged] Context. The CoRoT space mission has been searching for transiting planets since the end of December 2006. Aims. We aim to investigate the capability of CoRoT to detect…
Star-planet magnetic interaction and activity in late-type stars with close-in planets
A. F. Lanza
Late-type stars interact with their close-in planets through their coronal magnetic fields. We introduce a theory for the interaction between the stellar and planetary fields focus…
Doppler tomography of transiting exoplanets: A prograde, low-inclined orbit for the hot Jupiter CoRoT-11b
Davide Gandolfi, Andrew Collier Cameron, Michael Endl +8
We report the detection of the Doppler shadow of the transiting hot Jupiter CoRoT-11b. Our analysis is based on line-profile tomography of time-series, Keck/HIRES high-resolution s…
Magnetic field, differential rotation and activity of the hot-Jupiter hosting star HD 179949
R. Fares, J. -F. Donati, C. Moutou +9
HD 179949 is an F8V star, orbited by a giant planet at ~8 R* every 3.092514 days. The system was reported to undergo episodes of stellar activity enhancement modulated by the orbit…
Current state of the modelling of photospheric activity
A. F. Lanza
I briefly review the current state of the modelling of photospheric activity based on the high-precision optical light curves obtained with MOST, CoRoT, and Kepler. These models ca…
Determination of rotation periods in solar-like stars with irregular sampling: the Gaia case
E. Distefano, A. C. Lanzafame, A. F. Lanza +4
We present a study on the determination of rotation periods (P) of solar-like stars from the photometric irregular time-sampling of the ESA Gaia mission, currently scheduled for la…
Multiwavelength flux variations induced by stellar magnetic activity: effects on planetary transits
P. Ballerini, G. Micela, A. F. Lanza +1
Stellar magnetic activity is a source of noise in the study of the transits of extrasolar planets. It induces flux variations which affect significantly the transit depth determina…
