Abstract
An interaction of a pseudoscalar particle with two photons induced by an external electromagnetic field is used to study the photon decay where a is a pseudoscalar particle associated with the Peccei-Quinn U(1) symmetry. The field-induced axion emission by photon is analyzed as a possible source of energy losses by astrophysical objects.
