Differential rotation in rapidly rotating early-type stars. I. Motivations for combined spectroscopic and interferometric studies
J. Zorec, Y. Fremat, A. Domiciano de Souza +7
Since the external regions of the envelopes of rapidly rotating early-type stars are unstable to convection, a coupling may exist between the convection and the internal rotation.…
Photometric variability of the Be star CoRoT-ID 102761769
M. Emilio, L. Andrade, E. Janot-Pacheco +16
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…
Evolution of massive Be and Oe stars at low metallicity towards the Long Gamma Ray bursts\footnote{Based on ESO runs 069.D-0275(A), 072.D-0245(A) and (C).}
Christophe Martayan, Jean Zorec, Dietrich Baade +3
Several studies have shown recently that at low metallicity B-type stars rotate faster than in environments of high metallicity. This is a typical case in the SMC. As a consequence…
Massive Oe/Be stars at low metallicity: Candidate progenitors of long GRBs?
Christophe Martayan, Dietrich Baade, Jean Zorec +3
At low metallicity the B-type stars rotate faster than at higher metallicity, typically in the SMC. As a consequence, it was expected a larger number of fast rotators in the SMC th…
High-angular resolution observations of the Pistol Star
Christophe Martayan, Ronny Blomme, Jean-Baptiste Le Bouquin +15
First results of near-IR adaptive optics (AO)-assisted imaging, interferometry, and spectroscopy of this Luminous Blue Variable (LBV) are presented. They suggest that the Pistol St…
Review about populations of Be stars: stellar evolution of extreme stars
Christophe Martayan, Thomas Rivinius, Dietrich Baade +2
Among the emission-line stars, the classical Be stars known for their extreme properties are remarkable. The Be stars are B-type main sequence stars that have displayed at least on…
