Fast radio bursts from axion stars moving through pulsar magnetospheres

arXiv:2004.06486 · doi:10.1103/PhysRevD.103.043015

Abstract

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 composed of eV axions can account for most of the mysterious fast radio bursts.
