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…

Irregularly Sampled Time Series Interpolation for Detailed Binary Evolution Simulations

Philipp M. Srivastava, Ugur Demir, Aggelos Katsaggelos +14

Modeling of large populations of binary stellar systems is an intergral part of a many areas of astrophysics, from radio pulsars and supernovae to X-ray binaries, gamma-ray bursts,…

The Formation of Black Holes in Non-interacting, Isolated Binaries. Gaia Black Holes as Calibrators of Stellar Winds From Massive Stars

Matthias U. Kruckow, Jeff J. Andrews, Tassos Fragos +10

Context. The black holes discovered using Gaia, especially Gaia BH1 and BH2, have low mass companions of solar-like metallicity in wide orbits. For standard isolated binary evoluti…

The effect of mass loss in models of red supergiants in the Small Magellanic Cloud

E. Zapartas, S. de Wit, K. Antoniadis +16

The rate and mechanism of mass loss of red supergiants (RSGs) remain poorly understood, especially at low metallicities. Motivated by the new empirical prescription by Yang et al.…

Emulators for stellar profiles in binary population modeling

Elizabeth Teng, Ugur Demir, Zoheyr Doctor +14

Knowledge about the internal physical structure of stars is crucial to understanding their evolution. The novel binary population synthesis code POSYDON includes a module for inter…

Active Learning for Computationally Efficient Distribution of Binary Evolution Simulations

Kyle Akira Rocha, Jeff J. Andrews, Christopher P. L. Berry +13

Binary stars undergo a variety of interactions and evolutionary phases, critical for predicting and explaining observed properties. Binary population synthesis with full stellar-st…

POSYDON: A General-Purpose Population Synthesis Code with Detailed Binary-Evolution Simulations

Tassos Fragos, Jeff J. Andrews, Simone S. Bavera +22

Most massive stars are members of a binary or a higher-order stellar systems, where the presence of a binary companion can decisively alter their evolution via binary interactions.…
