Description

We study the axionic field structure inside magnetized neutron stars where a non-vanishing magnetic field is present. Typically magnetic field strength may be as large as 1e15 G in the surface for magnetars and a few orders of magnitude larger in the very central core. We explore the additional effect of a tiny electric field under the non-perfect conductor approximation using hypothetical scalar or pseudoscalar axion nature. We find that phenomenological constraints from neutron stars yield an effective constraint on the coupling and axion mass parameter space.
