Distinct neutrino signatures and onset condition of quark deconfinement in accretion-induced collapse of white dwarfs
Juno C. L. Chan, Harry Ho-Yin Ng, Patrick Chi-Kit Cheong
We present the first general relativistic, neutrino-radiation hydrodynamics simulations of accretion-induced collapse (AIC) extending to seconds after core bounce, using realistic…
Influence of neutrino-electron scattering and neutrino-pair annihilation on hypermassive neutron star
Patrick Chi-Kit Cheong, Francois Foucart, Harry Ho-Yin Ng +4
We investigate the influence of inelastic neutrino microphysics in general-relativistic magnetohydrodynamics simulations of a hypermassive neutron star. In particular, we include s…
General-relativistic resistive-magnetohydrodynamics simulations of self-consistent magnetized rotating neutron stars
Patrick Chi-Kit Cheong, Antonios Tsokaros, Milton Ruiz +4
We present the first general-relativistic resistive magnetohydrodynamics simulations of self-consistent, rotating neutron stars with mixed poloidal and toroidal magnetic fields. Sp…
Energy-dependent and energy-integrated two-moment general-relativistic neutrino transport simulations of hypermassive neutron star
Patrick Chi-Kit Cheong, Francois Foucart, Matthew D. Duez +3
We compare two-moment based \emph{energy-dependent} and 3 variants of \emph{energy-integrated} neutrino transport general-relativistic magnetohydrodynamics simulations of hypermass…
Robustness of neutron star merger simulations to changes in neutrino transport and neutrino-matter interactions
Francois Foucart, Patrick Chi-Kit Cheong, Matthew D. Duez +3
Binary neutron star mergers play an important role in nuclear astrophysics: their gravitational wave and electromagnetic signals carry information about the equation of state of co…
Stability of hypermassive neutron stars with realistic rotation and entropy profiles
Nishad Muhammed, Matthew D. Duez, Pavan Chawhan +7
Binary neutron star mergers produce massive, hot, rapidly differentially rotating neutron star remnants; electromagnetic and gravitational wave signals associated with the subseque…
High angular momentum hot differentially rotating equilibrium star evolutions in conformally flat spacetime
Patrick Chi-Kit Cheong, Nishad Muhammed, Pavan Chawhan +5
The conformal flatness approximation to the Einstein equations has been successfully used in many astrophysical applications such as initial data constructions and dynamical simula…
Fundamental modes of rotating neutron stars with various degrees of differential rotation in dynamical spacetimes
Anson Ka Long Yip, Patrick Chi-Kit Cheong, Tjonnie Guang Feng Li
Violent astrophysical events, including core-collapse supernovae and binary neutron star mergers, can result in rotating neutron stars with diverse degrees of differential rotation…
