The twin red giant branch system BD+20 5391 A case study of low-mass double-core evolution

M. Kurpas, M. Dorsch, S. Geier +12

Understanding interactions of binary systems on the red giant branch is crucial to understanding the formation of compact stellar remnants such as helium-core white dwarfs (He-WDs)…

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…

Characterisation of B-type stars in four young Galactic open clusters. I. Stellar content and binary properties

Federica Nardini, Julia Bodensteiner, Hugues Sana +3

Multiplicity among massive stars represents a major uncertainty in stellar evolution theory, because the extra physical processes that it introduces significantly impacts each star…

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…

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…
