Be stars in open clusters in the Small Magellanic Cloud

Christophe Martayan, Dietrich Baade, Anne-Marie Hubert +4

We report on the study of the population of B and Be stars in SMC young clusters, performed with the Wide Field Imager in slitless spectroscopic mode at ESO/T2.2m with a filter cen…

Effects of metallicity, star-formation conditions, and evolution in B and Be stars. II: Small Magellanic Cloud, field of NGC 330

Christophe Martayan, Yves Frémat, Anne-Marie Hubert +3

We search for effects of metallicity on B and Be stars in the Small and Large Magellanic Clouds (SMC and LMC) and in the Milky Way (MW). We extend our previous analysis of B and Be…

First direct detection of a Keplerian rotating disk around the Be star Arae using the VLTI/AMBER instrument

Anthony Meilland, Philippe Stee, Martin Vannier +9

Aims. We aim to study the geometry and kinematics of the disk around the Be star Arae as a function of wavelength, especially across the Br emission line. The main purpose o…

Effects of metallicity, star formation conditions and evolution of B & Be stars

Christophe Martayan, Anne-Marie Hubert, Michele Floquet +3

To study the effects of metallicity and evolution on the appearance of the Be phenomenon in the B stars population, we observed several fields in the Large and Small Magellanic Clo…

Effects of metallicity, star formation conditions and evolution in B and Be stars. I: Large Magellanic Cloud, field of NGC 2004

Christophe Martayan, Yves Fremat, Anne-Marie Hubert +3

Spectroscopic observations of hot stars belonging to the young cluster LMC-NGC 2004 and its surrounding region were carried out with the VLT-GIRAFFE facilities in MEDUSA mode. We d…

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…
