dc.descriptionWe have measured radial velocities of a star, OGLE-TR-56, which shows a 1.2-day transit-like light curve found photometrically by Udalski et al.(2002ab). Here we show that the velocity changes we detect are probably induced by an object of 0.9 Jupiter masses - a very close-in gas-giant planet only 0.023 AU from its star, with a planetary radius of 1.3 Jupiter radii and a mean density of 0.5 g/cm3. At its small orbital distance, OGLE-TR-56b is hotter than any known planet, approaching 1900K, but it is stable against long-term evaporation or tidal disruption.
