The imprint of individual neutron star spins on ejecta, -process nucleosynthesis, and kilonovae in binary neutron star mergers
Beyhan Karakas, Rahime Matur, David Radice +2
To leading order, the gravitational-wave (GW) signal from binary neutron stars depends on the individual spins, and , only through the effective spin parameter $χ_{\rm e…
Hyperaccreting Magnetised Neutron Stars inside Rotating Massive Envelopes: Low-Power Jets and Precursor Flares
Patrick Chi-Kit Cheong, Christopher L. Fryer, David Radice
The engulfment of a neutron star (NS) by a massive companion initiates a highly dynamic common-envelope (CE) evolution phase. As the NS spirals into the dense stellar core, it is s…
From Multimessenger Inference to Simulations: A Ranked Ensemble of Finite-Temperature Equations of State
Max Jacobi, Giulia Huez, Sebastiano Bernuzzi +1
We construct a set of microphysical, finite-temperature equations of state (EOSs) for numerical simulations of neutron star mergers and core-collapse supernovae that is consistent…
Magnetar Formation from Accretion Induced Collapse of White Dwarfs
Luís Felipe Longo Micchi, Patrick Chi-Kit Cheong, David Radice
We aim to characterize the post-collapse evolution of accretion-induced collapse (AIC) remnants of rapidly rotating, magnetized white dwarfs, focusing on their rotational, magnetic…
Exact Mass Conservation in Binary Neutron Star Merger Simulations
Boris Daszuta, Sebastiano Bernuzzi, Joan Fontbuté +4
A long-standing problem in the simulation of neutron star spacetimes is the treatment of vacuum regions outside the stars. The use of an artificial low-density atmosphere is a comm…
Hyperaccreting Neutron Stars inside Massive Envelopes: The Implausibility of Thorne-Żytkow Objects
Patrick Chi-Kit Cheong, David Radice, Christopher L. Fryer
The evolution of neutron stars (NSs) embedded within massive stellar envelopes is a critical phase in binary stellar evolution, potentially leading to the formation of Thorne-Żytko…
Gamma-ray Signatures of r-Process Radioactivity from the Collapse of Magnetized White Dwarfs
Tetyana Pitik, Yong-Zhong Qian, David Radice +1
We predict the gamma-ray line emission from -process nuclei synthesized in the ejecta of the accretion-induced collapse (AIC) of a magnetized, rapidly rotating white dwarf. Usin…
GR-Athena++: Binary Neutron Star Merger Simulations with Neutrino Transport
Boris Daszuta, Sebastiano Bernuzzi, Maximilian Jacobi +4
We present general-relativistic radiation magnetohydrodynamics simulations of binary neutron star mergers performed with GR-Athena++. Neutrino transport is treated using a moment-b…
Collapse of Magnetized White Dwarfs as site of Heavy Element Formation and Kilonova Signal
Tetyana Pitik, David Radice, Daniel Kasen +3
We present the first end-to-end calculation connecting the accretion-induced collapse (AIC) of a magnetized, rapidly rotating white dwarf to observable kilonova signatures, combini…
