Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign

T. Shenar, J. Bodensteiner, M. Abdul-Masih +73

The BLOeM campaign presents the first large‑scale spectroscopic survey of 929 massive stars in the Small Magellanic Cloud, revealing a high intrinsic binary fraction (>70%) among m…

Interacting binaries on the Main Sequence as in-situ tracers of mass transfer efficiency and stability

Koushik Sen, Mathieu Renzo, Harim Jin +8

Understanding the transfer of mass and angular momentum in binary interactions is crucial for modelling the evolution of any interacting binary after the first mass transfer phase.…

Subgiants in NGC 188 Reveal that Rotationally Induced Mixing Creates the Main Sequence Li-Dip

Qinghui Sun, Constantine P. Deliyannis, Barbara J. Anthony-Twarog +3

The "Li-Dip" is an unexpected, striking, and highly non-standard anomaly of severe lithium depletion observed in mid-F dwarf stars, which has puzzled astronomers for nearly 40 year…

Using detailed single star and binary evolution models to probe the large observed luminosity spread of red supergiants in young open star clusters

Chen Wang, Lee Patrick, Abel Schootemeijer +12

Red supergiants (RSGs) represent a late evolutionary stage of massive stars. Recent observations reveal that the observed luminosity range of RSGs in young open clusters is wider t…
