Binarity at LOw Metallicity (BLOeM): massive star variability revealed using a novel software tool for point-spread function fitting of TESS images

Pieterjan J. Van Daele, Dominic M. Bowman, Roey Ovadia +12

Massive stars, the progenitors of neutron stars and black holes, play a crucial role in shaping the chemical and radiative properties of entire galaxies through their winds and exp…

Hidden massive eclipsing binaries in red supergiant systems: The hierarchical triple system KQ Puppis and other candidates

D. Jadlovský, L. Molnár, A. Ercolino +26

The majority of massive stars are part of binary systems that may interact during their evolution. However, not many RSGs are known binaries, and only a few have constrained orbita…

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…

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 drastic impact of Eddington-limit induced mass ejections on massive star populations

D. Pauli, N. Langer, A. Schootemeijer +6

Massive stars are the key engines of the Universe. However, their evolution and thus their ionizing feedback are still not fully understood. One of the largest gaps in current stel…

Binarity at LOw Metallicity (BLOeM): a spectroscopic VLT monitoring survey of massive stars in the SMC

T. Shenar, J. Bodensteiner, H. Sana +74

Surveys in the Milky Way and Large Magellanic Cloud revealed that the majority of massive stars will interact with companions during their lives. However, knowledge of the binary p…
