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…
ALMA measurements of mass loss and wind clumping in the massive stars of the Arches cluster
James P. Perry, Raman K. Prinja, Danielle M. Fenech +1
We present the first Atacama Large Millimeter/submillimeter Array (ALMA) Band 3 (100 GHz) and Band 6 (243 GHz) continuum observations of the Arches cluster, one of the youngest and…
The IACOB project: XVI. Surface helium abundances in Galactic O-type stars: indications for identifying binary interaction products
S. Simón-DÃaz, G. Holgado, C. MartÃnez-Sebastián +13
The presence of massive O-type stars with surfaces enriched by CNO-cycle products has been known since the early 1980s. For many years, internal rotational mixing was assumed to be…
X-Shooting ULLYSES: Massive stars at low metallicity XV. On the metallicity dependence of B-supergiant mass-loss rates
O. Verhamme, J. O. Sundqvist, A. de Koter +21
Context. For stellar evolution models we rely on mass-loss rate prescriptions that show features that lack empirical confirmation, such as the bi-stability jump. This jump is an in…
EWOCS-V: Is Wd1-72 a recent post-interaction WR+O binary?
C. J. K. Larkin, J. Mackey, H. Jin +14
The evolutionary origin of Wolf-Rayet (WR) stars at Solar metallicity is unclear. Single-star evolution from massive O stars, possibly via a Luminous Blue Variable phase, is challe…
The winds of OBA hypergiants and luminous blue variables: Dynamically-consistent atmosphere models reveal multiple wind regimes
Matheus Bernini-Peron, Andreas A. C. Sander, Gautham N. Sabhahit +3
OBA hypergiants (OBAHGs) are evolved massive stars with notable wind features in their optical spectrum. Located at the cool edge of the line-driven wind regime, many are candidate…
