Abstract Using recent improved results on the frequency and polarization dependent opacities in a strong magnetic field we examine the physics of the lower accretion column on a magnetic neutron star to determine the spectrum radiated at infinity. We argue that photon convection by the fast infalling material (free fall velocities ∼ c/2) should substantially modify the spectrum radiated through the accretion column due to the frequency dependence of the opacity.
