A Multidimensional General-Relativistic Boltzmann Solver for Neutrino Transport: Implementation, Discretization and Optimization
Arthur Offermans, Harry Ho-Yin Ng, Patrick Chi-Kit Cheong +2
We present the implementation of a multidimensional general-relativistic Boltzmann solver for neutrino transport using the finite volume method. We extend the general-relativistic…
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…
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…
Impact of neutrino-electron scattering and an improved treatment of pair processes on binary neutron star mergers
Francois Foucart, Samantha Rath, Rowan Davidson +5
Multimessenger observations of neutron star mergers are unique opportunities to constrain the properties of dense matter and the production site of heavy nuclei. To leverage these…
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…
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…
