On the possible observational manifestation of supernova shock impact on the neutron star magnetosphere

TL;DR

This paper explores how supernova shocks impacting neutron star magnetospheres could produce observable phenomena, such as short, bright radio bursts, through magnetic reconnection and plasma instabilities.

Contribution

It presents a novel model linking supernova shock interactions with neutron star magnetospheres to observable radio bursts, expanding understanding of transient astrophysical phenomena.

Findings

Supernova shocks can create magnetospheric tails with significant magnetic energy.

Magnetic reconnection can accelerate particles, producing radio emission.

Plasma instabilities may generate millisecond radio bursts similar to observed FRBs.

Abstract

Impact of supernova explosion on the neutron star magnetosphere in a massive binary system is considered. The supernova shock striking the NS magnetosphere filled with plasma can lead to the formation of a magnetospheric tail with significant magnetic energy. The magnetic field reconnection in the current sheet formed can convert the magnetic energy stored in the tail into kinetic energy of accelerated charged particles. Plasma instabilities excited by beams of relativistic particles can lead to the formation of a short pulse of coherent radio emission with parameters similar to those of the observed bright extragalactic millisecond radio burst (Lorimer et al. 2007).
