The Tarantula massive binary monitoring VII. The nature of the eccentric O+BH binary candidate VFTS 812

K. Deshmukh, H. Sana, O. Verhamme +9

Massive O-type stars () with an X-ray quiet black hole (BH) companion represent a crucial stage in massive binary evolution leading to binary BH mergers. The p…

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 drastic impact of Eddington-limit induced mass ejections on massive star populations

D. Pauli, N. Langer, A. Schootemeijer +6

Massive stars are the key engines of the Universe. However, their evolution and thus their ionizing feedback are still not fully understood. One of the largest gaps in current stel…

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…

New gravitational-wave data support a bimodal black-hole mass distribution

R. Willcox, F. R. N. Schneider, E. Laplace +7

Detailed stellar evolution and supernova models yield a bimodal black-hole mass distribution with a narrow peak around 10 solar masses from stars within a narrow range of progenito…
