UBVRI CCD photometry of the old open cluster NGC 6253 ⋆
We present UBVRI photometry for the old open cluster NGC 6253. From comparison of the observed colour-magnitude diagrams with simulations based on stellar evolutionary models we derive in a self consistent way reddening, distance, and age of the cluster: E(B−V)= 0.23–0.32, (m-M)0 = 10.9±0.1, metallicity roughly double than solar, and age ≃ 3 Gyr. The cluster has a binary sequence, discernible e...
متن کاملCCD photometry of the old open cluster Collinder 261 ⋆
We present UBVI photometry for the old open cluster Collinder 261. From comparison of the observed colour-magnitude diagrams with simulations based on stellar evolutionary models we derive in a self consistent way reddening, distance, and age of the cluster: E(B−V)=0.25−0.34, (m-M)0=11.7-12.0, and age=7−8 Gyr or 9−11 Gyr, depending on the adopted stellar tracks. The models in better agreement w...
متن کاملCCD photometry of two old open clusters NGC 1798 and NGC 2192
We present UBV I CCD photometry of two open clusters NGC 1798 and NGC 2192 which were little studied before. Color-magnitude diagrams of these clusters show several features typical for old open clusters: a well-defined main-sequence, a red giant clump, and a small number of red giants. The main sequence of NGC 1798 shows a distinct gap at V ≈ 16.2 mag. From the surface number density distribut...
متن کاملPhotometry of the Open Cluster NGC 6791
We present the results from a three night, time-series study of the open cluster NGC 6791 using the Megacam wide-field mosaic CCD camera on the 6.5m MMT 1 telescope. The aim of this study was to demonstrate the ability to obtain very high precision photometry for a large number of stars. We achieved better than 1% precision for more than 8000 stars with 14.3 < R < 20.1 and sub-millimagnitude (a...
متن کاملCcd Photometry of Distant Open Clusters: Ii { Ngc 6791
Three new photometric CCD-based datasets are presented for NGC 6791. They consist of deep UBV photometry (to V lim = 24, B lim = 24, U lim = 23) of the central parts of the cluster and of selected elds around it, and of relatively shallower UBVI photometry for the whole cluster (23 0 23 0). The data have been used to discuss the reddening, metallicity and age of NGC 6791, a cluster which is par...
