We study the radio signals generated when an axion star enters the
magnetosphere of a neutron star. As the axion star moves through the resonant
region where the plasma-induced photon mass becomes equal to the axion mass,
the axions can efficiently convert into photons, giving rise to an intense,
transient radio signal. We show that a dense axion star with a mass $sim
10^{-13}M_{odot}$ composed of $sim 10: mu$eV axions can account for most of
the mysterious fast radio bursts.
