Abstract. The next generation of high-contrast imaging instruments will provide the first unre-
solved image of an extrasolar planet. While the emitted infrared light from the planet in thermal
equilibrium should show almost no phase effect, the reflected visible light will vary with the or-
bital phase angle. We study the photometric variation of the reflected light with orbital phase
of a ringed extrasolar planet. We show that a ring around an extrasolar planet, both obviously
