Axion Clouds around Neutron Stars

Recent work has shown that axions can be efficiently produced via nonstationary pair plasma discharges in the polar cap region of pulsars. Here, we point out that for axion masses 10^{−9}≲m_{a}≲10^{−4}  eV a sizable fraction of the sourced axion population will be gravitationally confined to the neu...
