K. Abstract Type : Invited Abstract Category : Stars,ISM and the Galaxy Abstract : The formation processes of massive OB stars and young stellar clusters are still poorly understood. In recent years, the study of the triggered star formation through the cloud-cloud collision (CCC) process is an interesting and important issue in the star formation research. It has also been suggested that the CCC process can form massive OB stars and young stellar clusters at the junction of molecular clouds. The onset of the CCC process in a given star-forming region could be observationally inferred through the detection of a bridge feature connecting the two clouds in velocity space, the broad CO line wing in the intersection of the two clouds, and the complementary distribution of the two colliding clouds. However, the investigation of observational signatures of star formation (including massive stars) via the CCC mechanism is still rare and very challenging. A multi-wavelength approach has been effectively used as a promising observational tool for understanding the ongoing physical processes in the Galactic star-forming regions. In this talk, new observational results of an analysis of some promising Galactic star-forming regions (such as G35.20-0.74, Sh2-235, bubble N49) will be presented, where the star formation activities (including massive stars) appear to be influenced by the CCC mechanism at the junction. |
