Present and Near-Future Reflected Light Searches for Close-In Planets
  Close-in extrasolar giant planets may be directly detectable by their reflected light, due to the proximity of the planet to the illuminating star. The spectrum of the system will contain a reflected light component that varies in amplitude and Doppler shift as the planet orbits the star. Intensive searches for this effect have been carried out for only one extrasolar planet system, tau Boo. There exist several other attractive targets, including the transiting planet system HD 209458.
