We present new observations of the transiting system TrES-3 obtained from 2009 to 2011 at several observatories. The orbital parameters of the system were redetermined and a new linear ephemeris was calculated. The best quality light curve was used for light-curve analysis, and other data sets were used to determine mid-transit times (Tc) and study transit time variation (TTV). For planet parameter determination we used two independent codes and finally, we concluded that our parameters are in...[Show more]
