The seismology programme of CoRoT
E. Michel, A. Baglin, M. Auvergne +1
We introduce the main lines and specificities of the CoRoT Seismology Core Programme. The development and consolidation of this programme has been made in the framework of the CoRo…
Circumstellar rings, flat and flaring discs
M. L. Arias, J. Zorec, Y. Frémat
Emission lines formed in the circumstellar envelopes of several type of stars can be modeled using first principles of line formation. We present simple ways of calculating line em…
Rotation in the ZAMS: Be and Bn stars
J. Zorec, Y. Frémat, C. Martayan +2
We show that Be stars belong to a high velocity tail of a single B-type star rotational velocity distribution in the MS. This implies that: 1) the number fraction N(Be)/N(Be+B) is…
B and Be stars in the Magellanic Clouds: rotation, evolution and variability
Christophe Martayan, Michele Floquet, Yves Fremat +3
Thanks to observations at the ESO VLT with the GIRAFFE multifibers spectrograph, we have obtained spectra of 177 and 346 B-type stars in the Large and Small Magellanic Clouds respe…
Effects of gravitational darkening on the determination of fundamental parameters in fast rotating B-type stars
Y. Fremat, J. Zorec, A. -M. Hubert +1
In this paper we develop a calculation code to account for the effects carried by fast rotation on the observed spectra of early-type stars. Stars are assumed to be in rigid rotati…
Spectral disentangling of the triple system DG Leo: orbits and chemical composition
Y. Fremat, P. Lampens, H. Hensberge
DG Leo is a spectroscopic triple system composed by 3 stars of late-A spectral type, one of which was suggested to be a delta Scuti star. Seven nights of observations at high spect…
