Using the linear polarimetric observations, we present a method to derive the
membership probability of stars in cluster NGC 2345. The polarimetric
observations of cluster NGC 2345 are performed using the instrument ARIES
IMaging POLarimeter (AIMPOL) mounted as a backend of the 104-cm telescope of
ARIES. Members of the cluster should exhibit comparable polarization since they
are located nearly at the same distance. This concept is used to extract the
membership probability of known member stars of cluster NGC 2345. The
membership probability estimated using the polarimetric data for cluster NGC
2345 agrees with the membership probability derived from the proper motion
method in the previous studies.
