Abstract

We show a possible origin of fast radio bursts. They arise from the collisions between axion stars and neutron stars. The bursts are emitted in atmospheres of the neutron stars. The observed frequencies of the bursts are given by the axion mass ma such as ma/2π2.4GHz(ma/105eV). By the comparison of the theoretical with observed event rate 103 per year in a galaxy, we can determine the mass 1012M of the axion stars. The mass is identical to the one estimated as the masses of axion miniclusters. Using these values, we can explain short durations (ms) and amount of radiation energies (1043  GeV) of the bursts.
