Oscillations of highly magnetized non-rotating neutron stars

M. Y. Leung, A. K. L. Yip, et al.

This groundbreaking research by Man Yin Leung, Anson Ka Long Yip, Patrick Chi-Kit Cheong, and Tjonnie Guang Feng Li explores the intricate pulsation modes of non-rotating neutron stars influenced by strong toroidal magnetic fields. Discover how stellar oscillations remain stable until an astonishing magnetic-to-binding energy threshold is crossed, resulting in significant frequency suppression due to the deformation of these compact celestial bodies.

Abstract

This paper investigates pulsation modes of non-rotating neutron stars with strong purely toroidal magnetic fields (10<sup>15-17</sup> G) using 2D axisymmetric general-relativistic magnetohydrodynamics simulations. The study reveals that stellar oscillations are unaffected by magnetization until the magnetic-to-binding energy ratio exceeds 10%, at which point pulsation mode frequencies are significantly suppressed. This suppression is attributed to the reduction in stellar compactness caused by the extreme magnetic fields' deformation of the neutron stars.
