Abstract:
We 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 2.4x10-4, 5.0x10-4, and
8.6x10-4 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.
Description:
We observed TrES-3 on six different nights when planetary occultations
were expected. On 2007 April 27, 2007 July 4, 2007 September 14, and
2008 March 12, we used the 1.2m telescope at the Fred L. Whipple
Observatory (FLWO) on Mount Hopkins, Arizona. On UT 2007 August 26 and
2007 October 3, we used the 1m telescope at Wise Observatory in
Israel.
