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 (…

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 binary landscape of massive stars at low : Insights from the BLOeM Campaign
J. I. Villaseñor, H. Sana, J. Bodensteiner +4
We present an overview of our recent results from the BLOeM campaign in the Small Magellanic Cloud (). Using nine-epoch VLT/FLAMES spectroscopy, we investig…
A family of binaries with an extreme mass ratio
Yael Naze, Gregor Rauw, Piotr A. Kolaczek-Szymanski +2
Multiplicity is ubiquitous among massive stars. While the stellar components usually display similar masses, some binaries with extremely low mass ratios were also observed. Some o…
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…
Analysis of mass-transferring binary candidates in the Milky Way
G. Garcia-Moreno, N. Blagorodnova, F. Anders +4
Mass transfer between stars in binary systems profoundly impacts their evolution, yet many aspects of this process (especially the stability, mass loss, and eventual fate of such s…
Investigating episodic mass loss in evolved massive stars: III. Spectroscopy of dusty massive stars in three northern galaxies
S. de Wit, G. Muñoz-Sanchez, G. Maravelias +6
Mass loss in massive stars is crucial to understanding how these stars evolve and explode. Despite increasing evidence indicating its importance, episodic mass loss remains poorly…
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…
Using detailed single star and binary evolution models to probe the large observed luminosity spread of red supergiants in young open star clusters
Chen Wang, Lee Patrick, Abel Schootemeijer +12
Red supergiants (RSGs) represent a late evolutionary stage of massive stars. Recent observations reveal that the observed luminosity range of RSGs in young open clusters is wider t…
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…
TESS observations of non-Be fast rotators
Yael Naze, Nikolay Britavskiy, Jonathan Labadie-Bartz
The variability of fast-rotating Oe/Be stars has been reported in detail in recent years. However, much less known about the behaviour of fast-rotating OB stars without known decre…
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…
The IACOB project: CVIII. Hunting for spectroscopic binaries in the O and B supergiant domain.The threat of pulsational variability
S. Simón-Díaz, N. Britavskiy, N. Castro +2

S. de Wit, A. Z. Bonanos, K. Antoniadis +8
Mass loss during the red supergiant (RSG) phase plays a crucial role in the evolution of an intermediate massive star, however, the underlying mechanism remains unknown. We aim to…
Tracing the evolution of short-period binaries with super-synchronous fast rotators
N. Britavskiy, M. Renzo, Y. Nazé +2
