Revealing Optically Hidden Companions to Intermediate-Mass Stripped Stars with Radial Velocities
Alexander Laroche, Maria R. Drout, Ylva Götberg +7
The recent discovery of a population of intermediate-mass helium stars (2-8 ) in the Magellanic Clouds has opened a new observational window into massive binary evol…
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…
The Stripped-Star Ultraviolet Magellanic Cloud Survey (SUMS): The UV Photometric Catalog and Stripped Star Candidate Selection
Bethany Ludwig, Maria R. Drout, Ylva Gotberg +2
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$…
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…
Binary Yellow Supergiants in the Magellanic Clouds I: Photometric Candidate Identification
Anna J. G. O'Grady, Maria R. Drout, Kathryn F. Neugent +3
Recent works have constrained the binary fraction of evolved populations of massive stars in local galaxies such as red supergiants and Wolf-Rayet stars, but the binary fraction of…
X-Shooting ULLYSES: Massive Stars at Low Metallicity
Jorick S. Vink, Paul Crowther, Alex Fullerton +20
The Hubble Space Telescope has devoted 500 orbits to observing 250 massive stars with low metallicity in the ultraviolet (UV) range within the framework of the ULLYSES program. The…
The B-type Binaries Characterisation Programme II. VFTS 291: A stripped star from a recent mass transfer phase
J. I. Villaseñor, D. J. Lennon, A. Picco +12
Recent studies of massive binaries with putative black hole companions have uncovered a phase of binary evolution that has not been observed before, featuring a bloated stripped st…
Discovery of the missing intermediate-mass helium stars stripped in binaries
M. R. Drout, Y. Götberg, B. A. Ludwig +4
The theory of binary evolution predicts that many massive stars should lose their hydrogen-rich envelopes via interaction with a companion -- revealing hot helium stars with masses…
X-Shooting ULLYSES: massive stars at low metallicity. I. Project Description
Jorick S. Vink, A. Mehner, P. A. Crowther +78
Observations of individual massive stars, super-luminous supernovae, gamma-ray bursts, and gravitational-wave events involving spectacular black-hole mergers, indicate that the low…
The effects of surface fossil magnetic fields on massive star evolution: IV. Grids of models at Solar, LMC, and SMC metallicities
Z. Keszthelyi, A. de Koter, Y. Götberg +12
Magnetic fields can drastically change predictions of evolutionary models of massive stars via mass-loss quenching, magnetic braking, and efficient angular momentum transport, whic…
