摘要: Context. Searching for planets in open clusters allows us to study the effects of dynamical environment on planet formation and evolution. Aims. Considering strong dependence frequency stellar metallicity, we studied metal rich old cluster NGC 6791 searched close-in using transit technique. Methods. A ten-night observational campaign was performed Canada-France-Hawaii Telescope (3.6 m), San Pedro Martir telescope (2.1 Loiano (1.5 m). To increase detection probability also made use Bruntt et al. (2003, AA (ii) a smaller planetary radius orbiting super stars; or (iii) limitations basic assumptions. More extensive photometry with 3–4 m class telescopes is required allow conclusive inferences about 6791.
