A Galactic intermediate-mass stripped star with a Wolf-Rayet-like wind
Johanna Müller-Horn, Kareem El-Badry, Andreas A. C. Sander +17
Binary interaction in massive stars is expected to produce a large population of intermediate-mass (- M) envelope-stripped stars, yet such objects have remained elusi…
Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign
T. Shenar, J. Bodensteiner, M. Abdul-Masih +73
Massive stars at low metallicity (Z) play a central role in shaping the high-redshift Universe, yet their multiplicity remains poorly constrained. The Binarity at Low Metallicity (…
Combining REBOUND and MESA: Dynamical Evolution of Planets Orbiting Interacting Binaries
Zepei Xing, Santiago Torres, Ylva Götberg +3
Although planets have been found orbiting binary systems, whether they can survive binary interactions is debated. While the tightest-orbit binaries should host the most dynamicall…
Tidal Disruption Events from Stripped Stars
Brenna Mockler, Monica Gallegos-Garcia, Ylva Götberg +2
Observations of tidal disruption events (TDEs) show signs of Nitrogen enrichment reminiscent of other astrophysical sources such as active galactic nuclei (AGN) and star-forming ga…
The young massive SMC cluster NGC 330 seen by MUSE III. Stellar parameters and rotational velocities
J. Bodensteiner, H. Sana, P. L. Dufton +11
The origin of initial rotation rates of stars, and how a star's surface rotational velocity changes during the evolution, either by internal angular momentum transport or due to in…
Stellar properties of observed stars stripped in binaries in the Magellanic Clouds
Y. Gotberg, M. R. Drout, A. P. Ji +6
Massive stars (~8-25Msun) stripped of their hydrogen-rich envelopes via binary interaction are thought to be the main progenitors for merging neutron stars and stripped-envelope su…
Observational predictions for Thorne-Żytkow objects
R. Farmer, M. Renzo, Y. Götberg +3
Thorne-ytkow objects (TO) are potential end products of the merger of a neutron star with a non-degenerate star. In this work, we have computed the first grid of evolutionary…
Bringing Stellar Evolution & Feedback Together: Summary of proposals from the Lorentz Center Workshop, 2022
Sam Geen, Poojan Agrawal, Paul A. Crowther +34
Stars strongly impact their environment, and shape structures on all scales throughout the universe, in a process known as ``feedback''. Due to the complexity of both stellar evolu…
A Panchromatic Study of Massive Stars in the Extremely Metal-Poor Local Group Dwarf Galaxy Leo A
Maude Gull, Daniel R. Weisz, Peter Senchyna +17
We characterize massive stars (M>8 M_sun) in the nearby (D~0.8 Mpc) extremely metal-poor (Z~5% Z_sun) galaxy Leo A using Hubble Space Telescope ultra-violet (UV), optical, and near…
Cool, Luminous, and Highly Variable Stars in the Magellanic Clouds. II: Spectroscopic and Environmental Analysis of Thorne-Żytkow Object and Super-AGB Star Candidates
Anna J. G. O'Grady, Maria R. Drout, B. M. Gaensler +9
In previous work we identified a population of 38 cool and luminous variable stars in the Magellanic Clouds and examined 11 in detail in order to classify them as either Thorne-Żyt…
Pre-Explosion Properties of Helium Star Donors to Thermonuclear Supernovae
Tin Long Sunny Wong, Josiah Schwab, Ylva Götberg
Helium star - carbon-oxygen white dwarf (CO WD) binaries are potential single-degenerate progenitor systems of thermonuclear supernovae. Revisiting a set of binary evolution calcul…
Evolution of accretor stars in massive binaries: broader implications from modeling ζ Ophiuchi
M. Renzo, Y. Gotberg
Most massive stars are born in binaries close enough for mass transfer episodes. These modify the appearance, structure, and future evolution of both stars. We compute the evolutio…
Different to the core: the pre-supernova structures of massive single and binary-stripped stars
E. Laplace, S. Justham, M. Renzo +4
The majority of massive stars live in binary or multiple systems and will interact during their lifetimes, which helps to explain the observed diversity of core-collapse supernovae…
Extreme isolation of WN3/O3 stars and implications for their evolutionary origin as the elusive stripped binaries
Nathan Smith, Ylva Gotberg, Selma E. de Mink
Recent surveys of the Magellanic Clouds have revealed a subtype of Wolf-Rayet (WR) star with peculiar properties. WN3/O3 spectra exhibit both WR-like emission and O3 V-like absorpt…
Delay-time distribution of core-collapse supernovae with late events resulting from binary interaction
E. Zapartas, S. E. de Mink, R. G. Izzard +8
Most massive stars, the progenitors of core-collapse supernovae, are in close binary systems and may interact with their companion through mass transfer or merging. We undertake a…
Ionizing spectra of stars that lose their envelope through interaction with a binary companion: role of metallicity
Y. Gotberg, S. E. de Mink, J. H. Groh
Understanding ionizing fluxes of stellar populations is crucial for various astrophysical problems including the epoch of reionization. Massive short-lived Wolf-Rayet stars are gen…
