Strongly Magnetized Super-Eddington Accretion: How Spin and Accretion Rate Regulate Energy Output and Mass Loss

Tom Man Kwan, Lixin Dai, Cheuk Kwan Kan +5

Strongly magnetized super-Eddington accretion flows power many important astrophysical systems, but how black hole parameters control their output is unclear. We present 32 general…

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…

Stellar Population Spectra Incorporating Detailed Binary Evolution using POSYDON

Eirini Kasdagli, Jeff J. Andrews, Bret Lehmer +8

The accuracy of stellar population properties inferred through spectral energy distribution fitting hinges on the reliability of the underlying spectral models. Binary interactions…

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…
