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 (…

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…

Complex spectral variability and hints of a luminous companion in the Be star + black hole binary candidate ALS 8814

Kareem El-Badry, Matthias Fabry, Hugues Sana +2

The emission-line binary ALS 8814 was recently proposed as a Be star + black hole (BH) binary based on large-amplitude radial velocity (RV) variations of a Be star and non-detectio…

Binarity at LOw Metallicity (BLOeM): Bayesian inference of natal kicks from inert black hole binaries

R. Willcox, P. Marchant, A. Vigna-Gómez +15

Context. The emerging population of inert black hole binaries (BHBs) provides a unique opportunity to constrain black hole (BH) formation physics. These systems are composed of a s…

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) -- 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.…
