Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign

T. Shenar, J. Bodensteiner, M. Abdul-Masih +73

Massive stars at low metallicity (Z) play a central role in shaping the high-redshift Universe, yet their multiplicity remains poorly constrained. The Binarity at Low Metallicity (…

Binarity at LOw Metallicity (BLOeM): Projected rotational velocities

D. J. Lennon, S. R. Berlanas, A. Herrero +36

The Binarity at LOw Metallicity (BLOeM) survey is an ESO large programme designed to obtain multi-epoch spectroscopy for 929 massive stars in the Small Magellanic Cloud (SMC). It w…

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.…

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…

Binarity at LOw Metallicity (BLOeM): Pipeline-Determined Physical Properties of OB Stars

J. M. Bestenlehner, Paul A. Crowther, V. A. Bronner +8

We aim to determine the physical properties of OB stars from the multi-epoch VLT/FLAMES BLOeM spectroscopic survey of the Small Magellanic Cloud. We apply a pipeline designed to an…

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…

Populations of evolved massive binary stars in the Small Magellanic Cloud I: Predictions from detailed evolution models

X. -T. Xu, C. Schürmann, N. Langer +13

Context. The majority of massive stars are born with a close binary companion. How this affects their evolution and fate is still largely uncertain, especially at low metallicity.…

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…

Binarity at LOw Metallicity (BLOeM): The multiplicity properties and evolution of BAF-type supergiants

L. R. Patrick, D. J. Lennon, F. Najarro +36

Given the uncertain evolutionary status of blue supergiant stars, their multiplicity properties hold vital clues to better understand their origin and evolution. As part of The Bin…

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…

Red supergiant stars in binary systems II. Confirmation of B-type companions of red supergiants in the Small Magellanic Cloud using Hubble ultra-violet spectroscopy

L. R. Patrick, D. J. Lennon, A. Schootemeijer +5

Red supergiant stars (RSGs) represent the final evolutionary phase of the majority of massive stars and hold a unique role in testing the physics of stellar models. Eighty eight RS…

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…

Rotational synchronisation of B-type binaries in 30 Doradus

D. J. Lennon, P. L. Dufton, J. I. Villaseñor +4

The spin evolution of stars in close binary systems can be strongly affected by tides. We investigate the rotational synchronisation of the stellar components for 69 SB1 systems an…

The VLT-FLAMES Tarantula Survey XXV. Surface nitrogen abundances of O-type giants and supergiants

N. J. Grin, O. H. Ramirez-Agudelo, A. de Koter +19

Theoretically, rotation-induced chemical mixing in massive stars has far reaching evolutionary consequences, affecting the sequence of morphological phases, lifetimes, nucleosynthe…
