Beaming Binaries: A New Observational Category of Photometric Binary Stars
Mazeh, Tsevi; Zucker, Shay; Alexander, Tal
The new photometric spaceborne survey missions COROT and Kepler will be able to detect minute flux variations in binary stars due to relativistic beaming caused by the line-of-sight motion of their components. In all but very short period binaries (P>10 days), these variations will dominate over the ellipsoidal and reflection periodic variabili…
Could we identify hot ocean-planets with CoRoT, Kepler and Doppler velocimetry?
Sotin, C.; Barge, P.; Bordé, P. +16 more
Planets less massive than about 10 M are expected to have no massive H-He atmosphere and a cometary composition (∼50% rocks, 50% water, by mass) provided they formed beyond the snowline of protoplanetary disks. Due to inward migration, such planets could be found at any distance between their formation site and the star. If migration stops within …
Jitter Correction Algorithms for the COROT Satellite Mission: Validation with Test Bench Data and MOST On-Orbit Photometry
Auvergne, M.; Drummond, R.; Aerts, C. +5 more
We demonstrate the effectiveness and robustness of photometric correction algorithms for satellite pointing jitter in the upcoming space mission COROT, which will study asteroseismology and search for exoplanets. Two algorithms based on model-based estimation and decorrelation are tested in two ways: (1) with artificial light sources in the COROT …
Theoretical planetary mass spectra - a prediction for COROT
Broeg, C.
The satellite COROT will search for close-in exoplanets around a few thousand stars using the transit search method. The COROT mission holds the promise of detecting numerous exoplanets. Together with radial velocity follow-up observations, the masses of the detected planets will be known.
We have devised a method for predicting the expected …CoRoT data contribution to stellar seismology
Auvergne, M.; Baudin, F.; Michel, E. +2 more
At the time to submit papers for these proceedings, CoRoT will be launched in less than one month. The scientific programme, the instrument and the mission profile have been described in several places recently (e.g., Baglin et al. 2006, Michel et al. 2006a) and a dedicated volume (Fridlund et al. 2006) has been published, where these aspects are …
