Abstract
Gravitational lensing properties and the influence of the electric charge on the light curves of a slowly rotating neutron star whose exterior is described by the Reissner-Nordström metric are considered. The polar cap emission model is assumed. No effect of the magnetosphere except for its possible contribution to the total charge is taken into account. In general, the lensing effect is reduced by the charge and the light curves become more similar to those typical in flat space rather than to the Schwarzschild spacetime.
