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…
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…
Explodability fluctuations of massive stellar cores enable asymmetric compact object mergers such as GW190814
John Antoniadis, David R. Aguilera-Dena, Alejandro Vigna-Gómez +6
The first three observing runs with Advanced LIGO and Virgo have resulted in the detection of binary black hole mergers (BBH) with highly unequal mass components, which are difficu…
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…
Successful Common Envelope Ejection and Binary Neutron Star Formation in 3D Hydrodynamics
Jamie A. P. Law-Smith, Rosa Wallace Everson, Enrico Ramirez-Ruiz +10
A binary neutron star merger has been observed in a multi-messenger detection of gravitational wave (GW) and electromagnetic (EM) radiation. Binary neutron stars that merge within…
Accuracy of inference on the physics of binary evolution from gravitational-wave observations
Jim W. Barrett, Sebastian M. Gaebel, Coenraad J. Neijssel +5
The properties of the population of merging binary black holes encode some of the uncertain physics of the evolution of massive stars in binaries. The binary black hole merger rate…
