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…
The incidence of LBV variability in the LMC
V. M. Kalari, J. S. Vink, C. Furey +3
Luminous blue variables (LBVs) exhibit unique variability features, characterized by episodic outbursts (1 mag) accompanied by spectroscopic changes (S Dor variables). It is deb…
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…
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…
A new sample of massive B-type contact binary candidates from the OGLE survey of the Magellanic Clouds
Athira Menon, Michal Pawlak, Daniel J. Lennon +2
Massive contact binaries (CBs) are key to understanding close-binary evolution and stellar mergers, yet their study has been limited by the scarcity of observed systems, particular…
A high fraction of close massive binary stars at low metallicity
H. Sana, T. Shenar, J. Bodensteiner +74
At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…
