Wide binary pulsars from electron-capture supernovae
Simon Stevenson, Reinhold Willcox, Alejandro Vigna-Gomez +1
Neutron stars receive velocity kicks at birth in supernovae. Those formed in electron-capture supernovae from super asymptotic giant branch stars -- the lowest mass stars to end th…
Constraints on Weak Supernova Kicks from Observed Pulsar Velocities
Reinhold Willcox, Ilya Mandel, Eric Thrane +3
Observations of binary pulsars and pulsars in globular clusters suggest that at least some pulsars must receive weak natal kicks at birth. If all pulsars received strong natal kick…
Fallback supernova assembly of heavy binary neutron stars and light black hole-neutron star pairs and the common stellar ancestry of GW190425 and GW200115
Alejandro Vigna-Gómez, Sophie L. Schrøder, Enrico Ramirez-Ruiz +4
The detection of the unusually heavy binary neutron star merger GW190425 marked a stark contrast to the mass distribution from known Galactic pulsars in double neutron star binarie…
Impact of Massive Binary Star and Cosmic Evolution on Gravitational Wave Observations I: Black Hole-Neutron Star Mergers
Floor S. Broekgaarden, Edo Berger, Coenraad J. Neijssel +7
Mergers of black hole-neutron star (BHNS) binaries have now been observed by GW detectors with the recent announcement of GW200105 and GW200115. Such observations not only provide…
Wind mass-loss rates of stripped stars inferred from Cygnus X-1
Coenraad J. Neijssel, Serena Vinciguerra, Alejandro Vigna-Gomez +5
Recent observations of the high-mass X-ray binary Cygnus X-1 have shown that both the companion star (41 solar masses) and the black hole (21 solar masses) are more massive than pr…
Massive Stellar Triples Leading to Sequential Binary Black-Hole Mergers in the Field
Alejandro Vigna-Gómez, Silvia Toonen, Enrico Ramirez-Ruiz +3
Stellar triples with massive stellar components are common, and can lead to sequential binary black-hole mergers. Here, we outline the evolution towards these sequential mergers, a…
