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 sickleshaped hot spots arising as a possible result of Mandelstam–Raman scattering of the reflected radiation by returned positrons.

Анотація

Періодичні структури на полярних шапках, що виникають внаслідок нестійкості поверхні пульсара в сильному магнітному полі, можуть бути відповідальними як за появу додаткових компонентів у пульсарному випромінюванні, так і за утворення серпоподібних гарячих точок, що виникають як можливий результат розсіювання Мандельштама–Рамана відбитого випромінювання обернутими позитронами.

Key words: pulsars, Mandelstam–Raman scattering, Wood’s anomalies, sickle shape structures.
