Abstract:
We present z-band photometry of three consecutive transits of the
exoplanet TrES-1, with an accuracy of 0.15% and a cadence of 40s. We
improve on estimates of the system parameters, finding in particular
that the planetary radius is 1.081±0.029RJup and the stellar
radius is 0.011±0.020R☉. The uncertainties include both the
statistical error and the systematic error arising from the
uncertainty in the stellar mass. The transit times are determined to
within about 15s and allow us to refine the estimate of the mean
orbital period: P=3.0300737±0.0000026days. We find no evidence for
starspots or other irregularities that have been previously reported.
Description:
We observed three transits of TrES-1 (on UT 2006 June 9, 12, and 15),
corresponding to epochs E=234, 235, and 236 of the ephemeris given by
Alonso et al. (2004ApJ...613L.153A 2004ApJ...613L.153A):
TC(E)=2453186.8060[HJD]+E(3.030065days).
