Abstract : It is believed that the majority of stars form in clusters. Despite many theoretical and observational studies, no global consensus has been achieved yet on the formation and evolution of star clusters. In particular, how mass assembles at the cluster location, what governs the shape of the initial-mass-function (IMF), and what defines the star formation rate and efficiency at the cluster scale. IRAS 23545+6508, located at a distance of 1 kpc, is a probable cluster candidate inferred from the nebulosity seen in the shallow 2MASS observations. Literature results show that the cluster is a part of a dark cloud and is host to ionized and molecular outflows, implying that the cluster is indeed very young. With aim to understand the above-mentioned problems of clusters at their very early phases, we have obtained deep JHK images of the cluster with the TANSPEC camera mounted on the 3.6-m DOT. In this work, deep near-infrared images of the cluster will be presented. Along with the analysis of high-resolution radio continuum archival data obtained with VLA, the fundamental properties, evolutionary status, shape of the IMF, and the formation history of the clusters will also be discussed.
