Ultraviolet spectroscopy reveals a hot and luminous companion to the Be star+black hole candidate MWC 656
Johanna Müller-Horn, Varsha Ramachandran, Kareem El-Badry +11
The Galactic Be star binary MWC 656 was long considered the only known Be star+black hole (BH) system, making it a critical benchmark for models of massive binary evolution and for…
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…
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…
The Stripped-Star Ultraviolet Magellanic Cloud Survey (SUMS): The UV Photometric Catalog and Stripped Star Candidate Selection
Bethany Ludwig, Maria R. Drout, Ylva Gotberg +3
Most massive stars will interact with a binary companion during their lifetimes. These interactions can remove the hydrogen-rich envelope, producing intermediate-mass (2-8 M$…
The mass distribution of stars stripped in binaries: The effect of metallicity
B. Hovis-Afflerbach, Y. Götberg, A. Schootemeijer +4
Stars stripped of their hydrogen-rich envelopes through binary interaction are thought to be responsible for both hydrogen-poor supernovae and the hard ionizing radiation observed…
