The evolution of accretor stars in binary systems due to accretion of increasingly helium-rich material
Sean Richards, Jan Eldridge, Sohan Ghodla +1
The recent discovery of examples of intermediate-mass helium stars have offered new insights into interacting binaries. These observations will allow significant improvements in ou…
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…
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…
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…
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…
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,…
