Unveiling the nature of G6096: a likely hierarchical triple system
Yinghao Xu, Xinlin Zhao, Song Wang +10
G6096 (Gaia DR3 609651611028044544) was recently reported as a wide ( days) and eccentric () binary possibly hosting a massive white dwarf or neutron star. In…
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…
A Be star-black hole binary with a wide orbit from LAMOST time-domain survey
Qian-Yu An, Yang Huang, Wei-Min Gu +21
Binary systems consisting of an early type star and a black hole (BH) are crucial for understanding various astrophysical phenomena, particularly the origins of detected gravitatio…
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,…
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…
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…
Mass-gap Black Holes in Coalescing Neutron Star Black Hole Binaries
Zepei Xing, Vicky Kalogera, Tassos Fragos +10
The existence of a mass gap of between the heaviest neutron stars (NSs) and the lightest black holes (BHs), inferred from the BH mass distribution in low mass X-ra…
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…
Formation of Wind-Fed Black Hole High-mass X-ray Binaries: The Role of Roche-lobe-Overflow Post Black-Hole Formation
Zepei Xing, Tassos Fragos, Emmanouil Zapartas +12
The three dynamically confirmed wind-fed black hole high-mass X-ray binaries (BH-HMXBs) are suggested to all contain a highly spinning black hole (BH). However, based on the theori…
Wind Roche-lobe Overflow in Low-Mass Binaries: Exploring the Origin of Rapidly Rotating Blue Lurkers
Meng Sun, Sasha Levina, Seth Gossage +4
Wind Roche-Lobe Overflow (WRLOF) is a mass-transfer mechanism proposed by Mohamed and Podsiadlowski (2007) for stellar binaries wherein the wind acceleration zone of the donor star…
From ZAMS to Merger: Detailed Binary Evolution Models of Coalescing Neutron Star-Black Hole Systems at Solar Metallicity
Zepei Xing, Simone S. Bavera, Tassos Fragos +10
Neutron star black hole (NSBH) merger events bring us new opportunities to constrain theories of stellar and binary evolution, and understand the nature of compact objects. In…
Exploring the nature of ultra-luminous X-ray sources across stellar population ages using detailed binary evolution calculations
Devina Misra, Konstantinos Kovlakas, Tassos Fragos +8
Ultra-luminous X-ray sources (ULXs) are sources observed to exceed the Eddington limit of a stellar-mass black hole (BH). A fraction of ULX sources show X-ray pulses which are evid…
The formation of merging black holes at solar metallicity
Simone S. Bavera, Tassos Fragos, Emmanouil Zapartas +11
The maximum mass of black holes formed in isolated binaries is determined by stellar winds and the interactions between the binary components. We consider for the first time fully…
A Black Hole Kicked At Birth: MAXI J1305-704
Chase Kimball, Sam Imperato, Vicky Kalogera +12
When a compact object is formed in a binary, any mass lost during core collapse will impart a kick on the binary's center of mass. Asymmetries in this mass loss or neutrino emissio…
Investigating the Lower Mass Gap with Low Mass X-ray Binary Population Synthesis
Jared C. Siegel, Ilia Kiato, Vicky Kalogera +14
Mass measurements from low-mass black hole X-ray binaries (LMXBs) and radio pulsars have been used to identify a gap between the most massive neutron stars (NSs) and the least mass…
