Transient phenomena from gas-erupting neutron stars

TL;DR

This paper proposes that starquakes in neutron stars can cause internal gas to erupt into the magnetosphere, leading to transient phenomena, by analyzing the role of cracks and oscillation modes in the star.

Contribution

It introduces a novel mechanism linking starquakes and gas eruptions in neutron stars, explaining transient phenomena through internal gas dynamics.

Findings

Gas can erupt from neutron stars during starquakes.

Eruptions produce transient and bursting phenomena.

Cracks and oscillation modes influence eruption dynamics.

Abstract

Starquakes probably occur in rapidly spinning or ultra high field neutron stars. In this article, we argue that highly compressed gas containing electron-positron pairs could evaporate and erupt from inside the neutron star when a crack forms and then heals during a starquake. Under the influence of the existing oscillation modes of the star, the crack may have sufficiently large size and long lifetime. An appropriate amount of gas can erupt into the magnetosphere with relativistic and nearly uniform velocity, producing various transient and bursting phenomena.
