The observed polarization properties of thermal radiation from isolated,cooling neutron stars depend on both the emission processes at the surface andthe effects of the magnetized vacuum which surrounds the star. Here weinvestigate the polarized thermal emission from X-ray Dim Isolated NeutronStars, taking RX J1856.5-3754 as a representative case. The physical conditionsof the star outermost layers in these sources is still debated, and so weconsider emission from a magnetized atmosphere and a condensed surface,accounting for the effects of vacuum polarization as the radiation propagatesin the star magnetosphere. We have found that, for a significant range ofviewing geometries, measurement of the phase-averaged polarization fraction andphase-averaged polarization angle at both optical and X-ray wavelengths allowus to determine whether this neutron star has an atmosphere or a condensedsurface. Our results may therefore be relevant in view of future developmentsof soft X-ray polarimeters.
