Resonant conversion of photon modes due to vacuum polarization in a magnetized plasma: implications for X-ray emission from magnetars.

LAI D. and HO W.C.G.

Abstract (from CDS):

It is known that vacuum polarization can modify the photon propagation modes in the atmospheric plasma of a strongly magnetized neutron star. A resonance occurs when the effect of vacuum polarization on the photon modes balances that of the plasma. We show that a photon (with energy E≳ a few keV) propagating outward in the atmosphere can convert from one polarization mode into another as it traverses the resonant density, ρres≃Y–1eη–2(B/1014G)2(E/1keV)2 g.cm–3, where Ye is the electron fraction and η∼1 is a slowly varying function of the magnetic field B. The physics of this mode conversion is analogous to the Mikheyev-Smirnov-Wolfenstein mechanism for neutrino oscillation. Because the two photon modes have vastly different opacities in the atmosphere, this vacuum-induced mode conversion can significantly affect radiative transport and surface emission from strongly magnetized neutron stars.
