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 (…
The Tarantula massive binary monitoring VII. The nature of the eccentric O+BH binary candidate VFTS 812
K. Deshmukh, H. Sana, O. Verhamme +9
Massive O-type stars () with an X-ray quiet black hole (BH) companion represent a crucial stage in massive binary evolution leading to binary BH mergers. The p…
Binarity at LOw Metallicity (BLOeM): Projected rotational velocities
D. J. Lennon, S. R. Berlanas, A. Herrero +36
The Binarity at LOw Metallicity (BLOeM) survey is an ESO large programme designed to obtain multi-epoch spectroscopy for 929 massive stars in the Small Magellanic Cloud (SMC). It w…
The drastic impact of Eddington-limit induced mass ejections on massive star populations
D. Pauli, N. Langer, A. Schootemeijer +6
Massive stars are the key engines of the Universe. However, their evolution and thus their ionizing feedback are still not fully understood. One of the largest gaps in current stel…
HR6819: a puffed-up stripped star system challenging stable mass transfer theory
A. Picco, P. Marchant, H. Sana +8
HR6819 is the first system with a puffed-up low mass stripped star and a classical Be star whose nature has been confirmed by optical interferometry. It shows the most extreme mass…
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…
New gravitational-wave data support a bimodal black-hole mass distribution
R. Willcox, F. R. N. Schneider, E. Laplace +7
Detailed stellar evolution and supernova models yield a bimodal black-hole mass distribution with a narrow peak around 10 solar masses from stars within a narrow range of progenito…
Binarity at LOw Metallicity (BLOeM): Pipeline-Determined Physical Properties of OB Stars
J. M. Bestenlehner, Paul A. Crowther, V. A. Bronner +8
We aim to determine the physical properties of OB stars from the multi-epoch VLT/FLAMES BLOeM spectroscopic survey of the Small Magellanic Cloud. We apply a pipeline designed to an…
Binarity at LOw Metallicity (BLOeM): Bayesian inference of natal kicks from inert black hole binaries
R. Willcox, P. Marchant, A. Vigna-Gómez +15
Context. The emerging population of inert black hole binaries (BHBs) provides a unique opportunity to constrain black hole (BH) formation physics. These systems are composed of a s…
Evolution of binary stars
Pablo Marchant
Binary stars are pairs of stars that are gravitationally bound, providing in some cases accurate measurements of their masses and radii. As such, they serve as excellent testbeds f…
The highly magnetic Wolf-Rayet binary HD 45166 resolved with VLTI/GRAVITY
K. Deshmukh, T. Shenar, A. Mérand +9
HD 45166 was recently reported to be a long-period binary comprising a B7V star and a highly magnetic (kG) hot Wolf-Rayet-like component, dubbed a…
Populations of evolved massive binary stars in the Small Magellanic Cloud I: Predictions from detailed evolution models
X. -T. Xu, C. Schürmann, N. Langer +13
Context. The majority of massive stars are born with a close binary companion. How this affects their evolution and fate is still largely uncertain, especially at low metallicity.…
Constraining the overcontact phase in massive binary evolution -- III. Period stability of known B+B and O+B overcontact systems
Jasmine Vrancken, Michael Abdul-Masih, Ana Escorza +3
Binary systems play a crucial role in massive star evolution. Systems composed of B-type and O-type stars are of particular interest due to their potential to lead to very energeti…
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…
A magnetic massive star has experienced a stellar merger
A. J. Frost, H. Sana, L. Mahy +13
Massive stars (those larger than 8 solar masses at formation) have radiative envelopes that cannot sustain a dynamo, the mechanism that produces magnetic fields in lower-mass stars…
Modelling time-dependent convective penetration in 1D stellar evolution
Cole Johnston, Mathias Michielsen, Evan H. Anders +7
1D stellar evolution calculations produce uncertain predictions for quantities like the age, core mass, core compactness, and nucleo-synthetic yields; a key source of uncertainty i…
The Evolution of Massive Binary Stars
Pablo Marchant, Julia Bodensteiner
Massive stars play a major role in the evolution of their host galaxies, and serve as important probes of the distant Universe. It has been established that the majority of massive…
Detecting Stripped Stars While Searching for Quiescent Black Holes
J. Bodensteiner, M. Heida, M. Abdul-Masih +13
While the number of stellar-mass black holes detected in X-rays or as gravitational wave sources is steadily increasing, the known population remains orders of magnitude smaller th…
