The physics of strong magnetic fields in neutron stars
Qiu-he Peng, Hao Tong
TL;DR
This paper proposes that the intense magnetic fields observed in neutron stars originate from Pauli paramagnetization of the degenerate relativistic electron gas inside the star, explaining their super-strong magnetic fields naturally.
Contribution
It introduces a new mechanism where magnetic flux conservation and Pauli paramagnetization amplify magnetic fields during neutron star formation.
Findings
Magnetic field can be amplified over 90 times during neutron star formation.
Pauli paramagnetization explains the origin of neutron star magnetic fields.
Provides a natural explanation for observed super-strong magnetic fields.
Abstract
In this paper we present a new result, namely that the primal magnetic field of the collapsed core during a supernova explosion will, as a result of the conservation of magnetic flux, receive a massive boost to more than 90 times its original value by the Pauli paramagnetization of the highly degenerate relativistic electron gas just after the formation of the neutron star. Thus, the observed super-strong magnetic field of neutron stars may originate from the induced Pauli paramagnetization of the highly degenerate relativistic electron gas in the interior of the neutron star. We therefore have an apparently natural explanation for the surface magnetic field of a neutron star.
