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 (…
A magnetic tertiary in the most massive compact triple-star system
S. Hubrig, A. Vigna-Gómez, S. P. Järvinen +2
The system TIC 470710327 is comprised of three main-sequence OB stars, with an inner compact 1.10 d eclipsing binary and a non-eclipsing tertiary on a 52.04 d orbit. With the terti…
A fundamental limit to how close binary systems can get via stable mass transfer shapes the properties of binary black hole mergers
Jakub Klencki, Philipp Podsiadlowski, Norbert Langer +4
Mass transfer in binary systems is the key process in the formation of various classes of objects, including merging binary black holes (BBHs) and neutron stars. Orbital evolution…
Evidence of polar and ultralow supernova kicks from the orbits of Be X-ray binaries
Ruggero Valli, Selma E. de Mink, Stephen Justham +7
Supernovae, the explosive deaths of massive stars, create heavy elements and form black holes and neutron stars. These compact objects often receive a velocity at formation, a "kic…
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…
Binarity at Low Metallicity (BLOeM) -- Multiplicity properties of Oe and Be stars
J. Bodensteiner, T. Shenar, H. Sana +40
Rapidly rotating classical OBe stars have been proposed as the products of binary interactions, and the fraction of Be stars with compact companions implies that at least some are.…
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…
Thorne-Żytkow Objects
Anna J. G. O'Grady, Takashi J. Moriya, Mathieu Renzo +1
Interacting binary star systems play a critical role in many areas of astrophysics. One interesting example of a binary merger product are Thorne-Żytkow Objects (TŻOs), stars that…
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…
Population synthesis of Thorne-Żytkow objects: Rejuvenated donors and unexplored progenitors in the common envelope formation channel
K. Nathaniel, A. Vigna-Gómez, A. Grichener +3
Context. Common envelope evolution of a massive star and a neutron star companion has two possible outcomes: formation of a short-period binary (a potential gravitational wave sour…
Long-term Evolution of Binary Orbits Induced by Circumbinary Disks
Ruggero Valli, Christopher Tiede, Alejandro Vigna-Gómez +6
Circumbinary disks are found in a variety of astrophysical scenarios, spanning binary star formation to accreting supermassive black hole binaries. The interaction with a circumbin…
Hypercritical accretion during common envelopes in triples leading to binary black holes in the pair-instability-supernova mass gap
Enrique Moreno Méndez, Fabio De Colle, Diego López Cámara +1
Hydrodynamic studies of stellar-mass compact objects (COs) in a common envelope (CE)have shown that the accretion rate onto the CO is a few orders of magnitude below the Bondi-Hoyl…
Uncovering a hidden black hole binary from secular eccentricity variations of a tertiary star
Bin Liu, Daniel J. D'Orazio, Alejandro Vigna-Gómez +1
We study the dynamics of a solar-type star orbiting around a black hole binary (BHB) in a nearly coplanar system. We present a novel effect that can prompt a growth and significant…
Stripped-envelope stars in different metallicity environments. II. Type I supernovae and compact remnants
David R. Aguilera-Dena, Bernhard Müller, John Antoniadis +4
Stripped-envelope stars can be observed as Wolf-Rayet (WR) stars, or as less luminous hydrogen-poor stars with low mass loss rates and transparent winds. Both types are potential p…
Astrophysics with the Laser Interferometer Space Antenna
Pau Amaro Seoane, Jeff Andrews, Manuel Arca Sedda +156
The Laser Interferometer Space Antenna (LISA) will be a transformative experiment for gravitational wave astronomy, and, as such, it will offer unique opportunities to address many…
Stripped-Envelope Stars in Different Metallicity Environments I. Evolutionary Phases, Classification and Populations
David R. Aguilera-Dena, Norbert Langer, John Antoniadis +5
Massive stars that become stripped of their hydrogen envelope through binary interaction or winds can be observed either as Wolf-Rayet stars, if they have optically thick winds, or…
Explodability fluctuations of massive stellar cores enable asymmetric compact object mergers such as GW190814
John Antoniadis, David R. Aguilera-Dena, Alejandro Vigna-Gómez +6

Stellar response after stripping as a model for common-envelope outcomes
Alejandro Vigna-Gómez, Michelle Wassink, Jakub Klencki +3
Binary neutron stars have been observed as millisecond pulsars, gravitational-wave sources, and as the progenitors of short gamma-ray bursts and kilonovae. Massive stellar binaries…
