An internal mechanism for the anti-glitch observed in AXP 1E 2259+586

TL;DR

This paper proposes a simple internal mechanism to explain the anti-glitch observed in the magnetar AXP 1E 2259+586, contributing to understanding sudden spin-down events in neutron stars.

Contribution

It introduces a novel internal mechanism specifically designed to account for the anti-glitch phenomenon in magnetars.

Findings

Proposes an internal mechanism for anti-glitch events.

Provides a plausible explanation for sudden spin-down in AXP 1E 2259+586.

Enhances understanding of neutron star magnetic and rotational dynamics.

Abstract

Magnetars are fascinating objects that are thought to be neutron stars powered by their strong internal magnetic fields. Clear evidence of a sudden spin-down was detected in the Anomalous X-ray Pulsar AXP 1E 2259+586, an object cataloged as a magnetar. This event received the name "anti-glitch". In this work we present a simple internal mechanism which could account for the observed sudden spin-down of the star.
