摘要

Using our Satellite Laser Ranging (SLR) facility, our experience and our available equipment for Single Photon detection, we installed a Single Photon Counting Module (SPCM) to measure the photon flux of variable stars, and of stars with transiting exoplanets; these observations are intended as a complementary application to our standard SLR activities, to contribute observations to already known - and also to candidate - variable stars and stars with transiting exoplanets. While it is relatively easy to detect the large - in some cases up to 50% - variations of some stars, it is a challenge to detect the transiting exoplanets with this method; the decrease in photon flux here is only in the order of a few percent. In this paper, we present first results.
