New Lighthouse Model, Simulation Results (IMAGE) National Institutes of Natural Sciences Caption The new lighthouse model (a snapshot from Movie) and simulation results from the present research (inset on the right) are shown. In the simulation results, the red indicates stronger radiation, and the arrows show the directions of photon flow. In this figure, many photons are produced near the surface of the neutron star and escape from the side of the accretion column.
