Abstract
We present preliminary results of the international collaboration “TEP” aimed at monitoring photometrically the eclipsing binary CM Draconis. Planetary companions with more than ∼3 Earth radii should produce detectable occultations at the accuracy of our measurements. The observations started in spring 1994 and are still going on. Eight observatories have participated so far: Haute Provence (France), Lick (USA), La Palma (Spain), Rochester (USA), Skinakas (Greece), Taejon (Korea), Teide (Spain) and Wise (Israel). We have obtained a homogeneous dataset by using CCD detectors with standard broad-band filters (V and R) and maintaining always common reference stars between all the observatories. So far, we have obtained about 500 hours of effective integration time on CM Dra, distributed in ∼ 16000 CCD frames. We have analysed about 40% of the 94–95 database, and have found encouraging, albeit inconclusive, results.
