Abstract:
We present UBVIc CCD photometry of the young open cluster Stock 8 with
the aim of studying its basic properties such as the amount of
interstellar extinction, distance, age, stellar contents and initial
mass function (IMF). We also studied the star formation scenario in
this region. From optical data, the radius of the cluster is found to
be ∼6arcmin (∼3.6pc) and the reddening within the cluster region
varies from E(B-V)=0.40 to 0.60mag. The cluster is located at a
distance of 2.05±0.10kpc. Using Hα slitless spectroscopy
and Two Micron All Sky Survey (2MASS) near-infrared (NIR) data we
identified Hα emission and NIR-excess young stellar objects
(YSOs), respectively.
