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…
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…
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…
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…
Identifying and characterizing ultracool dwarfs ejected from post-encounter disintegrating systems
Alexandra K. P. Yip, Radostin Kurtev, David J. Pinfield +3
Disintegrating multiple systems have been previously discovered from kinematic studies of the catalogue. They are presumably the result of dynamical encounters taki…
Oscillations of Highly Magnetized Non-rotating Neutron Stars
Man Yin Leung, Anson Ka Long Yip, Patrick Chi-Kit Cheong +1
Highly magnetized neutron stars are promising candidates to explain some of the most peculiar astronomical phenomena, for instance, fast radio bursts, gamma-ray bursts, and superlu…
Formation of a magnetized hybrid star with a purely toroidal field from phase-transition-induced collapse
Anson Ka Long Yip, Patrick Chi-Kit Cheong, Tjonnie Guang Feng Li
Strongly magnetized neutron stars are popular candidates for producing detectable electromagnetic and gravitational-wave signals. Gravitational collapses of neutron stars triggered…
An extension of Gmunu: General-relativistic resistive magnetohydrodynamics based on staggered-meshed constrained transport with elliptic cleaning
Patrick Chi-Kit Cheong, David Yat Tung Pong, Anson Ka Long Yip +1
We present the implementation of general-relativistic resistive magnetohydrodynamics solvers and three divergence-free handling approaches adopted in the General-relativistic multi…
VVV High proper motion stars I. The catalogue of bright Ks < 13.5 stars
R. Kurtev, M. Gromadzki, J. C. Beamin +14
Knowledge of the stellar content near the Sun is important for a broad range of topics ranging from the search for planets to the study of Milky Way structure. The most powerful me…
Identifying the ejected population from disintegrating multiple systems
A. K. P. Yip, D. J. Pinfield, R. Kurtev +2
Kinematic studies of the Hipparcos catalogue have revealed associations that are best explained as disintegrating multiple systems, presumably resulting from a dynamical encounter…
