Possible detection of phase changes from the non-transiting planet HD 46375b by CoRoT
P. Gaulme, M. Vannier, T. Guillot +19
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…
HD 46375: seismic and spectropolarimetric analysis of a young Sun hosting a Saturn-like planet
P. Gaulme, S. Deheuvels, W. W. Weiss +13
HD 46375 is known to host a Saturn-like exoplanet orbiting at 0.04 AU from its host star. Stellar light reflected by the planet was tentatively identified in the 34-day CoRoT run a…
The universal red-giant oscillation pattern; an automated determination with CoRoT data
B. Mosser, K. Belkacem, M. J. Goupil +12
The CoRoT and Kepler satellites have provided thousands of red-giant oscillation spectra. The analysis of these spectra requires efficient methods for identifying all eigenmode par…
Plaskett's Star: Analysis of the CoRoT photometric data
L. Mahy, E. Gosset, F. Baudin +13
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 (…
Exploring the magnetic topologies of cool stars
J. Morin, J. -F. Donati, P. Petit +19
Magnetic fields of cool stars can be directly investigated through the study of the Zeeman effect on photospheric spectral lines using several approaches. With spectroscopic measur…
Detection of frequency spacings in the young O-type binary HD 46149 from CoRoT photometry
P. Degroote, M. Briquet, M. Auvergne +15
Using the CoRoT space based photometry of the O-type binary HD46149, stellar atmospheric effects related to rotation can be separated from pulsations, because they leave distinct s…
