Binarity at LOw Metallicity (BLOeM): massive star variability revealed using a novel software tool for point-spread function fitting of TESS images

Pieterjan J. Van Daele, Dominic M. Bowman, Roey Ovadia +12

Massive stars, the progenitors of neutron stars and black holes, play a crucial role in shaping the chemical and radiative properties of entire galaxies through their winds and exp…

Population synthesis of Be X-ray binaries in the Small Magellanic Cloud: Angular momentum recycling and stable mass transfer

Víctor López Oller, Boyuan Liu, Michela Mapelli +5

Be X-ray binaries (BeXRBs) are key laboratories to constrain binary interaction processes such as mass transfer, angular-momentum transport, and natal kicks. The Small Magellanic C…

Ultraviolet spectroscopy reveals a hot and luminous companion to the Be star+black hole candidate MWC 656

Johanna Müller-Horn, Varsha Ramachandran, Kareem El-Badry +11

The Galactic Be star binary MWC 656 was long considered the only known Be star+black hole (BH) system, making it a critical benchmark for models of massive binary evolution and for…

The Triple System V1371 Tau: An Eclipsing Binary with an Outer Be Star

Danilo F. Rocha, Marcelo Emilio, Jonathan Labadie-Bartz +10

Although triple systems are common, their orbital dynamics and stellar evolution remain poorly understood. We investigated the V1371 Tau system using TESS photometry, multi-epoch s…

HR6819: a puffed-up stripped star system challenging stable mass transfer theory

A. Picco, P. Marchant, H. Sana +8

HR6819 is the first system with a puffed-up low mass stripped star and a classical Be star whose nature has been confirmed by optical interferometry. It shows the most extreme mass…

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…
