STUDIES OF THE PRE-MAIN SEQUENCE STARS IN THE H II REGION Sh2-87

The molecular clouds, associated with H II regions and young embedded clusters, serve as the ideal targets to probe the formation of stars and star clusters. Studies of individual Galactic H II regions are important because they reveal the effects of the star formation process on the interstellar medium. Here, we present our ongoing studies on the characterisation and identification of the pre-main-sequence stars associated with the H II regions Sh2-87, a member of the Vulpecula OB association. We have used the new spectroscopic observational data from 2-m HCT and several archival catalogues, e.g., WISE, SPITZER, and UKIDSS. Low-resolution spectroscopic observations revealed the presence of a few massive (early-B) sources. Using the near-infrared and mid-infrared colour excess, numerous new young populations are identified, that suggest active star-formation activity toward this region. Using multi-wavelength datasets, an overall star formation activity will be presented here
