The lack of fast rotators in Cyg OB2. I. Insights from spectral reclassification of its B0 population
D. Galán-Diéguez, S. R. Berlanas, A. Herrero +4
Context. Cygnus OB2, in the Cygnus X complex -- one of the most active star-forming regions of the Galaxy -- hosts hundreds of O- and B-type stars at different evolutionary stages.…
Binarity at LOw Metallicity (BLOeM): a spectroscopic VLT monitoring survey of massive stars in the SMC
T. Shenar, J. Bodensteiner, H. Sana +74
Surveys in the Milky Way and Large Magellanic Cloud revealed that the majority of massive stars will interact with companions during their lives. However, knowledge of the binary p…
A high fraction of close massive binary stars at low metallicity
H. Sana, T. Shenar, J. Bodensteiner +74
At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…
The Gaia-ESO Survey: Projected Rotational Velocities of B stars in the Carina Nebula
W. Santos, S. Daflon, J. V. Sales Silva +19
The Carina Nebula is an active star-forming region with several open clusters rich in massive OB stars, thus making it an optimal target for studying stellar properties such as rot…
Binarity at LOw Metallicity (BLOeM): Enhanced multiplicity of early B-type dwarfs and giants at
J. I. Villaseñor, H. Sana, L. Mahy +32
Early B-type stars ( M) are frequently in multiple systems, as evidenced by spectroscopic campaigns in the Milky Way (MW) and the Large Magellanic Cloud (LMC). Pr…
Populations of evolved massive binary stars in the Small Magellanic Cloud II: Predictions from rapid binary evolution
C. Schürmann, X. -T. Xu, N. Langer +10
Massive star evolution plays a crucial role in astrophysics but bares large uncertainties. This problem becomes more severe by the majority of massive stars being born in close bin…
