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 such as . By the comparison of the theoretical with observed event rate per year in a galaxy, we can determine the mass 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 () and amount of radiation energies () of the bursts.
