Evolution of wide O star binaries through their LBV stage. Population synthesis with mass-ejection-driven orbital evolution
Xiao-Tian Xu, Philipp Podsiadlowski, Norbert Langer +6
Context. Long-period Wolf-Rayet (WR) star binaries produced by mass transfer are predicted to be abundant, but are observationally rare. This yields constraints on the evolution of…
Interacting binaries on the Main Sequence as in-situ tracers of mass transfer efficiency and stability
Koushik Sen, Mathieu Renzo, Harim Jin +8
Understanding the transfer of mass and angular momentum in binary interactions is crucial for modelling the evolution of any interacting binary after the first mass transfer phase.…
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…
Using detailed single star and binary evolution models to probe the large observed luminosity spread of red supergiants in young open star clusters
Chen Wang, Lee Patrick, Abel Schootemeijer +12
Red supergiants (RSGs) represent a late evolutionary stage of massive stars. Recent observations reveal that the observed luminosity range of RSGs in young open clusters is wider t…
Modeling contact binaries, III. Properties of a population of close, massive binaries
Matthias Fabry, Pablo Marchant, Norbert Langer +1
Among massive stars, binary interaction is the rule rather than the exception. The closest binaries, those with periods of less than about 10 days, undergo mass transfer during cor…
Stripped helium-star and compact object binaries in coeval populations -- predictions based on detailed binary evolution models
Chen Wang, Julia Bodensteiner, Xiao-Tian Xu +9
Massive stars mainly form in close binaries, where their mutual interactions can profoundly alter their evolutionary paths. Evolved binaries consisting of a massive OB-type main-se…
Whispering in the dark: Faint X-ray emission from black holes with OB star companions
Koushik Sen, Ileyk El Mellah, Norbert Langer +3
Context. Recent astrometric and spectroscopic surveys of OB stars have revealed a few stellar-mass black holes (BHs) with orbital periods as low as 10 days. No X-ray counterpart ha…
Hunting for red supergiant binaries: UVIT photometry of the SMC
L. R. Patrick, D. Thilker, D. J. Lennon +5
We present UVIT/Astrosat UV photometry of the RSG population of the Small Cloud galaxy (SMC). As RSGs are extremely faint in the far-UV, these observations directly probe potential…
X-ray emission from BH+O star binaries expected to descend from the observed galactic WR+O binaries
K. Sen, X. -T. Xu, N. Langer +3
In the Milky Way, 18 Wolf-Rayet+O (WR+O) binaries are known with estimates of their stellar and orbital parameters. Whereas black hole+O (BH+O) binaries are thought to evolve…
Modules for Experiments in Stellar Astrophysics (MESA): Binaries, Pulsations, and Explosions
Bill Paxton, Pablo Marchant, Josiah Schwab +10
We substantially update the capabilities of the open-source software instrument Modules for Experiments in Stellar Astrophysics (MESA). MESA can now simultaneously evolve an intera…
The HD5980 multiple system: Masses and evolutionary status
Gloria Koenigsberger, Nidia Morrell, D. John Hillier +5
New spectroscopic observations of the LBV/WR multiple system HD5980 in the Small Magellanic Cloud are used to address the question of the masses and evolutionary status of the two…
Single Rotating Stars and the Formation of Bipolar Planetary Nebula
G. Garcia-Segura, E. Villaver, N. Langer +2
We have computed new stellar evolution models that include the effects of rotation and magnetic torques under different hypothesis. The goal is to test if a single star can sustain…
The incidence of stellar mergers and mass gainers among massive stars
S. E. de Mink, H. Sana, N. Langer +2
Because the majority of massive stars are born as members of close binary systems, populations of massive main-sequence stars contain stellar mergers and products of binary mass tr…
The rotation rates of massive stars: the role of binary interaction through tides, mass transfer and mergers
S. E. de Mink, N. Langer, R. G. Izzard +2
Rotation is thought to be a major factor in the evolution of massive stars, especially at low metallicity, with consequences for their chemical yields, ionizing flux and final fate…
Massive binaries as the source of abundance anomalies in globular clusters
S. E. de Mink, O. R. Pols, N. Langer +1
Abundance anomalies observed in globular cluster stars indicate pollution with material processed by hydrogen burning. Two main sources have been suggested: asymptotic giant branch…
