SIX OCCULTATIONS OF THE EXOPLANET TrES-3.” The Astronomical Journal 136 (1): 267–71. https://doi.org/10.1088/0004-6256/136/1/267.0004-62561538-3881http://nrs.harvard.edu/urn-3:HUL.InstRepos:41417348We present photometry of the exoplanet host star TrES-3 spanning six occultations (secondary eclipses) of its giant planet. No flux decrements were detected, leading to 99%-confidence upper limits on the planet-to-star flux ratio of 2.4 x 10(-4), 5.0 x 10(-4), and 8.6 x 10(-4) in the i-, z-, and R-bands respectively. The corresponding upper limits on the planet's geometric albedo are 0.30, 0.62, and 1.07. The upper limit in the i-band rules out the presence of highly reflective clouds, and is only a factor of 2-3 above the predicted level of thermal radiation from the planet.en-USJournal Article2019-09-2710.1088/0004-6256/136/1/267
