Since 2008 we have run an observational program to accurately measure the\ncharacteristics of known exoplanet systems hosting close-in transiting giant\nplanets, i.e. hot Jupiters. Our study is based on high-quality photometric\nfollow-up observations of transit events with an array of medium-class\ntelescopes, which are located in both the northern and the southern\nhemispheres. A high photometric precision is achieved through the\ntelescope-defocussing technique. The data are then reduced and analysed in a\nhomogeneous way for estimating the orbital and physical parameters of both the\nplanets and their parent stars. We also make use of multi-band imaging cameras\nfor probing planetary atmospheres via the transmission-photometry technique. In\nsome cases we adopt a two-site observational strategy for collecting\nsimultaneous light curves of individual transits, which is the only completely\nreliable method for truly distinguishing a real astrophysical signal from\nsystematic noise. In this contribution we review the main results of our\nprogram.\n
