Title: Dynamical evolution and oscillation of highly magnetised compact objects
Speaker: Patrick Chi-Kit Cheong (The Chinese University of Hong Kong)
Abstract
Highly magnetised neutron stars with magnetic fields of 10^15−16 G are promising candidates to be the observed soft gamma repeaters and X-ray pulsars. On the other hand, oscillations of neutron stars are closely related to the composition, structure, and equation of state of the star. However, the studies of oscillations of magnetised neutron stars has not yet realized the observed order of field magnitude. The formation and behaviour of strongly magnetised compact objects are highly complex and relativistic that require numerical simulation to model accurately. We use a new multidimensional general-relativistic magnetohydrodynamics code Gmunu to investigate the evolution of magnetised neutron stars and the corresponding oscillation modes. In particular, we present the influence of magnetic fields on neutron-star evolution, the oscillation modes and gravitational-wave asteroseismology.
