Abstract

We analysed the public data of the CoRoT Long Run LRc10 looking for plan- etary candidates. In a first step we removed outliers and trends caused by stellar activity and instrumental problems. Then we applied the Box-fitting Least Squares (BLS) algorithm to detect periodic decreases in luminosity. From all the significative transit detections, we selected the ones that passed different checks. For the 7 planetary candidates found, we applied a new “ad hoc” normalization and fitted the orbital parameters, to verify their relia- bility. Using the stellar temperature information, we could estimate the dimensions that the candidates should have if confirmed. Our research method demonstrated to be sensitive to candidates with hypothetic dimension up to ∼3.5 REarth on stars of mag V≃14.
