Abstract:
In this paper we study the evolution of the core and corona of nine
open clusters using the projected radial density profiles derived from
homogeneous CCD photometric data obtained with the 105cm Kiso Schmidt
telescope. The age and galactocentric distance of the target clusters
vary from 16 to 2000Myr and 9 to 10.8kpc, respectively. Barring
Be 62, which is a young open cluster, other clusters show a uniform
reddening across the cluster region.
Description:
The broadband CCD photometric observations of clusters were carried
out from 2001 November 19 to 25 using the 105cm Schmidt telescope of
the Kiso Observatory.
