Binarity at Low Metallicity (BLOeM) -- Multiplicity properties of Oe and Be stars
J. Bodensteiner, T. Shenar, H. Sana +40
Rapidly rotating classical OBe stars have been proposed as the products of binary interactions, and the fraction of Be stars with compact companions implies that at least some are.…
Binarity at LOw Metallicity (BLOeM): Multiplicity of early B-type supergiants in the Small Magellanic Cloud
N. Britavskiy, L. Mahy, D. J. Lennon +32
The blue supergiant (BSG) domain contains a large variety of stars whose past and future evolutionary paths are still highly uncertain. Since binary interaction plays a crucial rol…
Going from 3D common-envelope simulations to fast 1D simulations
V. A. Bronner, F. R. N. Schneider, Ph. Podsiadlowski +1
One-dimensional (1D) methods for simulating the common-envelope (CE) phase offer advantages over three-dimensional (3D) simulations regarding their computational speed and feasibil…
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 magnetic massive star has experienced a stellar merger
A. J. Frost, H. Sana, L. Mahy +13
Massive stars (those larger than 8 solar masses at formation) have radiative envelopes that cannot sustain a dynamo, the mechanism that produces magnetic fields in lower-mass stars…
The young massive SMC cluster NGC 330 seen by MUSE III. Stellar parameters and rotational velocities
J. Bodensteiner, H. Sana, P. L. Dufton +11
The origin of initial rotation rates of stars, and how a star's surface rotational velocity changes during the evolution, either by internal angular momentum transport or due to in…
The VLT-FLAMES Tarantula Survey: Observational evidence for two distinct populations of massive runaway stars in 30 Doradus
H. Sana, O. H. Ramírez-Agudelo, V. Hénault-Brunet +17
Two main scenarios have been proposed for origin of massive runaway stars -- dynamical ejection or release from a binary at the first core collapse -- but their relative contributi…
