Microscopic magnetic dipole radiation in neutron stars

TL;DR

This paper proposes that microscopic magnetic dipole radiation from the ${}^3P_2$ neutron superfluid in neutron stars could serve as a novel heating mechanism, potentially explaining observed neutron star glitches.

Contribution

It introduces a new heating mechanism based on magnetic dipole radiation from neutron superfluid regions in neutron stars.

Findings

Magnetic dipole radiation can significantly heat neutron stars.

This mechanism may explain neutron star glitches.

The model aligns with observed neutron star behaviors.

Abstract

There is ${}^3P_2$ neutron superfluid region in NS (neutron star) interior. For a rotating NS, the ${}^3P_2$ superfluid region is like a system of rotating magnetic dipoles. It will give out electromagnetic radiation, which may provides a new heating mechanism of NSs. This heating mechanism plus some cooling agent may give sound explanation to NS glitches.
