The physical origin of the maximum stellar size
Gautham N. Sabhahit, Jorick S. Vink
The authors explain the observed maximum radius of the most massive stars as a result of a transition to an Eddington‑enhanced mass‑loss regime, reproducing the Humphreys‑Davidson…
Hydrodynamical mass-loss rates for very massive stars II. New theoretical mass-loss predictions at solar metallicity (Z = 0.02)
Gautham N. Sabhahit, Jorick S. Vink, Andreas A. C. Sander
The paper presents a new theoretical prescription for mass loss in very massive stars, based on a large grid of hydrodynamically consistent wind models that capture the dependence…
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…
Southern massive stars at high angular resolution: WR 25 is a massive hierarchical triple system
K. Deshmukh, L. Mahy, H. Sana +6
The paper reports the first interferometric resolution of the massive star system WR 25, revealing it as a hierarchical triple with a close WN6ha+O5 binary and a more distant O7 te…
Constraints on the Metallicity-dependent Explodability of Massive Stars from Galactic Chemical Evolution: Toward Alleviating the Red Supergiant Problem
Sojun Ono, Keiichi Maeda, Akihiro Suzuki
The authors integrate metallicity‑dependent massive‑star explodability prescriptions into galactic chemical evolution models, showing they reproduce observed elemental abundances a…
