Abstract

In the scientific literature of recent years, the processes of generation of axion-like particles by various configurations of electromagnetic fields and waves under astrophysical conditions have been studied. Much attention to these issues is due to the fact that in some cosmological models massive axion-like particles are considered as dark matter, and massless particles as dark energy. And although these particles have not yet been found experimentally, the study of the processes of emission of axion-like particles by electromagnetic fields and waves in astrophysical conditions is relevant to the construction of new cosmological models.

In this paper,photogeneration of massless axions, called arions, is studied during propagation of magnetodipolar electromagnetic radiation from a rotating pulsar or magnetar in the Coulomb field of a charged particle. It is shown that, as a result of the interaction of these electromagnetic fields, arions should arise, having a frequency that coincides with the frequency of the pulsar’s magnetodipole radiation.

An exact solution to the equation for the arion field is obtained, and the angular distribution is found for the arion fluxes emitted as a result of their photogeneration on Coulomb particles in the magnetospheres of pulsars and magnetars throughout space. It is shown that there is no forward emission of arions in the process under study.
