Investigation in the region of the open cluster Tr 14

CCD UBVRI imaging photometry was carried out in the area of Tr 14. For the first time, we can have an overall view of the lower main sequence of the cluster. It is fully confirmed the anomalous nature of the extinction law. The distance of Tr 14 is stated in d= 3100 pc while its age, derived by the...
