We present a comprehensive study of star formation toward the H II region Sharpless 155 (S155). Star-formation activities therein were investigated based on multi-wavelength data from optical to the far-infrared. The surface density distribution of selected 2MASS sources toward S155 indicates the existence of a compact cluster, which is spatially …
