Wide Field CCD photometry around nine open clusters
In this paper we study the evolution of core and corona of nine open clusters using the projected radial density profiles derived from homogeneous CCD photometric data obtained through the 105-cm Kiso Schmidt telescope. The age and galactocentric distance of the target clusters varies from 16 Myr to 2000 Myr and 9 kpc to 10.8 kpc respectively. Barring Be 62, which is young open cluster, other c...
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...
متن کاملCCD photometry of distant open clusters NGC 2425 , Haffner 10 and Czernik 29
We present BV I photometry for poorly known southern hemisphere open clusters: NGC 2425, Haffner 10 and Czernik 29. We have calculated the density profile and established the number of stars in each cluster. The colour-magnitude diagrams of the objects show a well-defined main sequence. However, the red giant clump is present only in NGC 2425 and Haffner 10. For these two clusters we estimated ...
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 کاملCCD photometry of young MC clusters I : NGC 2172 ?
We present a new CCD photometry for the young LMC cluster NGC 2172, giving B, V, I magnitudes for more than 600 stars within 70 ′′ from the cluster center, down to approximatelyV = 21 mag. After correction for completeness and field stars contamination, we discuss the cluster HR diagram and the MS luminosity function in the light of current evolutionary theories and in connection with the probl...
