Abstract:
To progress in galactic studies based on open clusters, e.g. cluster
formation rate or kinematical properties, one needs to improve the
number of open clusters observed. However, only half of the 1700 known
galactic open clusters have been properly observed so far, making any
statistical investigation insignificant, especially at larger
distances from the Sun. We study marginally investigated or neglected
open clusters with Bessell CCD BVR photometry, whose data were used to
fit isochrones to the individual color-magnitude diagrams. We examined
the galactic clusters Basel 11b, King 14 and Czernik 43, the last
being observed for the first time to this extent. As well as a careful
comparison to available photometry, their parameters such as age,
interstellar reddening, distance and apparent diameter were
determined. The obtained cluster properties were verified by near
infrared 2MASS data. The three investigated intermediate age clusters
are all located in the galactic disk with distances between 1.8 and
3.0kpc from the Sun.
Description:
Photometric CCD BVR measurements of objects within the open clusters
Basel 11b, King 14 and Czernik 43 were obtained at the Leopold Figl
Observatory for Astrophysics (Austria).
