The IACOB project XVIII. Prevalence of short-period binaries among Galactic helium rich O-type stars

C. Martínez-Sebastián, R. Gamen, O. G. Benvenuto +6

For decades, the origin of helium enrichment in O-type stars has remained an open question. In this study, we investigate the correlation between surface helium abundance and orbit…

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

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

Massive stars at low metallicity (Z) play a central role in shaping the high-redshift Universe, yet their multiplicity remains poorly constrained. The Binarity at Low Metallicity (…

SpecFANN: Spectral Fitting via Artificial Neural Networks I. A deep learning based fastwind emulator and fitting suite

M. Abdul-Masih, C. Hawcroft, T. Lechien +14

The importance of massive stars cannot be overstated: they are powerful probes of the early universe, play a vital role in the chemical and mechanical evolution of their host envir…

Binarity at LOw Metallicity (BLOeM): Projected rotational velocities

D. J. Lennon, S. R. Berlanas, A. Herrero +36

The Binarity at LOw Metallicity (BLOeM) survey is an ESO large programme designed to obtain multi-epoch spectroscopy for 929 massive stars in the Small Magellanic Cloud (SMC). It w…

The IACOB project: XVI. Surface helium abundances in Galactic O-type stars: indications for identifying binary interaction products

S. Simón-Díaz, G. Holgado, C. Martínez-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…
