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…
Magnetic effects on fundamental modes in rotating neutron stars with a purely toroidal magnetic field
Anson Ka Long Yip, Tjonnie Guang Feng Li
Electromagnetic and gravitational-wave signals from neutron stars are shaped by rapid rotation and strong magnetic fields. Determining these properties is essential to interpret su…
Gravitational wave signatures from the phase-transition-induced collapse of a magnetized neutron star
Anson Ka Long Yip, Patrick Chi-Kit Cheong, Tjonnie Guang Feng Li
Strong magnetic fields make neutron stars potential sources of detectable electromagnetic and gravitational-wave signals. Hence, inferring these magnetic fields is critical to unde…
Impact of rotation on magnetic field stability and orientation in isolated neutron stars
Fabrizio Venturi Piñas, Anson Ka Long Yip, Patrick Chi-Kit Cheong +1
Neutron stars are the most compact horizonless objects in the Universe, exhibiting the strongest known magnetic fields. They are potential sources of coincident gravitational waves…
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…
