From the Milky Way to the Early Universe: How Metallicity Shapes the Formation of Double Neutron Stars
Abhishek Chattaraj, Jeff J. Andrews, Monica Gallegos-Garcia +10
Among the compact binaries detected through gravitational wave (GW) emission, double neutron stars (DNSs) hold the unique distinction of having well-characterized local analogs in…
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…
Disk-Regulated Mass Transfer Between Rotating Non-Degenerate Stars: Insights from Be and sdOB Binaries
Zepei Xing, Tassos Fragos, Vicky Kalogera +3
Mass transfer between non-degenerate stars is a fundamental but still poorly understood process in binary evolution. The commonly used rotationally limited accretion prescription i…
Modelling the Future of Gaia Neutron Star-Main Sequence Binaries: From Eccentric Orbits to Millisecond Pulsar-White Dwarfs
Debatri Chattopadhyay, Kyle A. Rocha, Seth Gossage +3
We model the evolution of 21 Gaia neutron star (NS)-main-sequence binaries (orbital period -- days, eccentricity ) using binary evolutio…
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…
Mass Transfer in Eccentric Orbits with Self-consistent Stellar Evolution
Kyle Akira Rocha, Rachel Hur, Vicky Kalogera +12
We investigate Roche lobe overflow mass transfer (MT) in eccentric binary systems between stars and compact objects (COs), modeling the coupled evolution of both the star and the o…
