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

Understand

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.
