A high fraction of close massive binary stars at low metallicity
H. Sana, T. Shenar, J. Bodensteiner +74
At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…
Binarity at LOw Metallicity (BLOeM): Multiplicity of early B-type supergiants in the Small Magellanic Cloud
N. Britavskiy, L. Mahy, D. J. Lennon +32
The blue supergiant (BSG) domain contains a large variety of stars whose past and future evolutionary paths are still highly uncertain. Since binary interaction plays a crucial rol…
The Evolution of Massive Stellar Multiplicity in the Field I. Numerical simulations, long-term evolution and final outcomes
Holly P. Preece, A. Vigna-Gómez, A. S. Rajamuthukumar +2
We investigate how the multiplicity of binary, triple and quadruple star systems changes as the systems evolve from the zero-age main-sequence to the Hubble time. We find the chang…
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…
Development of convective envelopes in massive stars: Implications for gravitational wave sources
Amedeo Romagnolo, Jakub Klencki, Alejandro Vigna-Gomez +1
The structure of stellar envelopes strongly influences the course and outcome of binary mass transfer, in particular of common envelope (CE) evolution. Convective envelopes can mos…
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…
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…
X-Shooting ULLYSES: Massive Stars at low metallicity VIII. Stellar and wind parameters of newly revealed stripped stars in Be binaries
V. Ramachandran, A. A. C. Sander, D. Pauli +16
On the route towards merging neutron stars and stripped-envelope supernovae, binary population synthesis predicts a large number of post-interaction systems with massive stars that…
On the evolutionary nature of puffed-up stripped star binaries and their occurrence in stellar populations
Debasish Dutta, Jakub Klencki
The majority of massive stars are formed in multiple systems and will interact with companions via mass transfer. This interaction typically leads to the primary shedding its envel…
Stellar Black Holes and Compact Stellar Remnants
Guglielmo Costa, Martyna Chruślińska, Jakub Klencki +4
The recent observations of gravitational waves (GWs) by the LIGO-Virgo-KAGRA collaboration (LVK) have provided a new opportunity for studying our Universe. By detecting several mer…
Everything that glitters is not gold: V1315 Cas is not a dormant black hole
J. Zak, D. Jones, H. M. J. Boffin +11
The quest for quiet or dormant black holes has been ongoing since several decades. Ellipsoidal variables possibly indicate the existence of a very high-mass invisible companion and…
A partially stripped massive star in a Be binary at low metallicity: A missing link towards Be X-ray binaries and double neutron star mergers
V. Ramachandran, J. Klencki, A. A. C. Sander +4
Standard binary evolutionary models predict a significant population of core helium-burning stars that lost their hydrogen-rich envelope after mass transfer via Roche-lobe overflow…
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…
Spectroscopic and evolutionary analyses of the binary system AzV 14 outline paths toward the WR stage at low metallicity
D. Pauli, L. M. Oskinova, W. -R. Hamann +16
The origin of the observed population of Wolf-Rayet (WR) stars in low-metallicity (low-Z) galaxies, such as the Small Magellanic Cloud (SMC), is not yet understood. Standard, singl…
Partial-envelope stripping and nuclear-timescale mass transfer from evolved supergiants at low metallicity
Jakub Klencki, Alina G. Istrate, Gijs Nelemans +1
Stable mass transfer from a massive post-main sequence (post-MS) donor is thought to be a short-lived event of thermal-timescale mass transfer which strips the donor star of nearly…
It has to be cool: on supergiant progenitors of binary black hole mergers from common-envelope evolution
J. Klencki, G. Nelemans, A. G. Istrate +1
Common-envelope (CE) evolution in massive binary systems is thought to be one of the most promising channels for the formation of compact binary mergers. In the case of merging bin…
Massive donors in interacting binaries: effect of metallicity
Jakub Klencki, Gijs Nelemans, Alina G. Istrate +1
Metallicity is known to significantly affect the radial expansion of a massive star: the lower the metallicity, the more compact the star, especially during its post-MS evolution.…
