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…
A constant upper luminosity limit of cool supergiant stars down to the extremely low metallicity of I Zw 18
Abel Schootemeijer, Ylva Götberg, Norbert Langer +3
Stellar wind mass loss is often assumed to depend on their metallicity . Therefore, evolutionary models of massive stars at lower are able to retain more of their H-rich lay…
First spectroscopic identification of the main sequence in Westerlund 1
R. Castellanos, F. Najarro, M. Garcia +8
Being the most massive known young stellar cluster in the Milky Way, Westerlund 1 (Wd1) constitutes an ideal benchmark for understanding the evolution of massive stars. However, th…
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 binary landscape of massive stars at low : Insights from the BLOeM Campaign
J. I. Villaseñor, H. Sana, J. Bodensteiner +4
We present an overview of our recent results from the BLOeM campaign in the Small Magellanic Cloud (). Using nine-epoch VLT/FLAMES spectroscopy, we investig…
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…
