We propose in this work the study of the production of axions in stellar plasma medium through an external magnetic field. In the background field approximation, we can show that the presence of the external magnetic field induces a mixing between the photon and the axion, i.e. the so called Primakoff effect. Since the axion is one of the greatest candidates for dark matter, for being a neutral pseudo-scalar field, the Primakoff process constitutes a mechanism (or portal) to access the dark sector, which in turn provides us new perspectives beyond the standard model. In the high energies limit, observables like probabilities transitions and particles production rates were computed.
