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…
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…
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…
Evolution of binary stars
Pablo Marchant
Binary stars are pairs of stars that are gravitationally bound, providing in some cases accurate measurements of their masses and radii. As such, they serve as excellent testbeds f…
The highly magnetic Wolf-Rayet binary HD 45166 resolved with VLTI/GRAVITY
K. Deshmukh, T. Shenar, A. Mérand +9
HD 45166 was recently reported to be a long-period binary comprising a B7V star and a highly magnetic (kG) hot Wolf-Rayet-like component, dubbed a…
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.…
