Formation of heavy double neutron stars II: the role of heavy first-born neutron stars and low metallicity
Ashwathi Nair, Simon Stevenson
The high total mass of GW190425 challenges our understanding of double neutron star (DNS) formation, as no such heavy (\, M) DNS system has been observed in the Milk…
Implications of modern mass-loss rates for massive stars
JD Merritt, Simon Stevenson, Andreas Sander +7
Massive stars lose a significant fraction of their mass through stellar winds at various stages of their lives, including on the main sequence, during the red supergiant phase, and…
Binary population synthesis of the Galactic canonical pulsar population
Yuzhe Song, Simon Stevenson, Debatri Chattopadhyay +2
Pulsars are rapidly rotating neutron stars that emit radiation across the electromagnetic spectrum, from radio to gamma-rays. We use the rapid binary population synthesis suite COM…
Formation of heavy double neutron stars I: Eddington-limited accretion for a 1.4 neutron star at solar metallicity
Ashwathi Nair, Simon Stevenson
More than 30 Galactic double neutron star (DNS) binaries have now been identified through radio pulsar timing. The 24 DNSs in the Galactic field with measured total masses lie in t…
Rapid stellar and binary population synthesis with COMPAS: methods paper II
Ilya Mandel, Jeff Riley, Adam Boesky +13
The COMPAS public rapid binary population synthesis code has undergone a number of key improvements since the original COMPAS methods paper (Team COMPAS: Riley et al., 2022) was pu…
