High-mass binary black hole mergers from detailed binary evolution models
Max M. Briel, Olcay Bıyıklı, Tassos Fragos +10
The paper uses detailed binary evolution simulations to test whether super‑Eddington mass transfer in isolated binaries can produce the observed high‑mass binary black hole mergers…
Forming Double Neutron Stars using Detailed Binary Evolution Models with POSYDON: Comparison to the Galactic Systems
Abhishek Chattaraj, Jeff J. Andrews, Simone S. Bavera +14
With over two dozen detections in the Milky Way, double neutron stars (DNSs) provide a unique window into massive binary evolution. We use the POSYDON binary population synthesis c…
Double Neutron Star Delay Times Across Cosmic Metallicities: The Role of Helium Star Progenitors
Abhishek Chattaraj, Jeff J. Andrews, Max Briel +5
Metallicity can play a significant role in massive binary evolution through its impact on the opacity within stellar interiors and wind-driven mass loss. In this work, we investiga…
A case for Case A: detailed look at binary black hole formation through stable mass transfer
Max M. Briel, Tassos Fragos, Monica Gallegos-Garcia +8
In isolated binary evolution, binary black hole (BBH) mergers are generally formed through stable mass transfer (SMT) or common envelope evolution. In recent years, the SMT channel…
POSYDON Version 2: Population Synthesis with Detailed Binary-Evolution Simulations across a Cosmological Range of Metallicities
Jeff J. Andrews, Simone S. Bavera, Max Briel +21
Whether considering rare astrophysical events on cosmological scales or unresolved stellar populations, accurate models must account for the integrated contribution from the entire…
