2011/9/27
The detection of pulsational frequencies in stellar photometry is required as input for asteroseismological modelling. The second short run (SRa02) of the CoRoT mission has provided photometric data o...
Plaskett's Star: Analysis of the CoRoT photometric data
Plaskett's Star the CoRoT photometric data
2011/1/10
The SRa02 of the CoRoT space mission for Asteroseismology was partly devoted to stars belonging to the Mon OB2 association. An intense monitoring was performed on Plaskett's Star (HD47129) and the unp...
Photometric variability of the Be star CoRoT-ID 102761769
Photometric variability the Be star CoRoT-ID
2011/1/11
Classical Be stars are rapid rotators of spectral type late O to early A and luminosity class V-III, wich exhibit Balmer emission lines and often a near infrared excess originating in an equatorially ...
Warm Spitzer Photometry of the Transiting Exoplanets CoRoT-1 and CoRoT-2 at Secondary Eclipse

2010/11/10
We measure secondary eclipses of the hot giant exoplanets CoRoT-1 at 3.6 and 4.5 μm, and CoRoT-2 at 3.6 μm, both using Warm Spitzer. We find that the Warm Spitzer mission is working very well for exop...
On planetary mass determination in the case of super-Earths orbiting active stars. The case of the CoRoT-7 system
CoRoT-7b CoRoT-7c mass determination exoplanets super-Earths
2010/11/12
Context. Due to the great contribution of the star activity in the measured radial velocities, the masses of CoRoT-7b and CoRoT 7c are very uncertain. Therefore, we are dealing with the typical proble...
Possible detection of phase changes from the non-transiting planet HD 46375b by CoRoT
Stars:planetary systems Techniques: photometric Methods: data analysis Stars: individual HD 46375
2010/11/15
Context. The present work deals with the detection of phase changes in an exoplanetary system. HD 46375 is a solar analog known to host a non-transiting Saturn-mass exoplanet with a 3.0236 day period....
