The spectrum of the B[e] star BAL224
Christophe Martayan, Michele Floquet, Anne-Marie Hubert +1
We present optical spectroscopy of the emission line star BAL 224 (V=17.3, B-V=0.46). This star also named KWBBE 485, [MA93]906 is located at the periphery of the young SMC cluster…
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…
A study of the B and Be star population in the field of the LMC open cluster NGC2004 with VLT-FLAMES
Christophe Martayan, Anne-Marie Hubert, Michele Floquet +5
Observations of hot stars belonging to the young cluster LMC-NGC2004 and its surrounding region have been obtained with the VLT-GIRAFFE facilities in MEDUSA mode. 25 Be stars were…
Fundamental parameters of Be stars located in the seismology fields of COROT
Yves Y. Fremat, Coralie Neiner, Anne-Marie Hubert +4
In preparation for the COROT space mission, we determined the fundamental parameters (spectral type, temperature, gravity, vsini) of the Be stars observable by COROT in its seismol…
