Instability of the pulsar surface in strong constant fields and generation of additional components due to combination scattering

Abstract

Periodic structures on polar caps, arising due to instability of the pulsar surface in a strong magnetic field, can be responsible both for the appearance of additional components in pulsar radiation and the formation of sickle shaped hot spots arising as a possible result of Mandelstam–Raman scattering of the reflected radiation by returned positrons.
