However, the feedback processes of massive stars on their vicinity are still poorly understood. The sites of massive stars are accessible to longer wavelengths (such as mid-, far-infrared, and radio) observations with very good spatial resolution. Earlier, it was observationally difficult to study the proposed problem using optical and near-infrared data alone. Now we have advantage of new observations at mid- and far-infrared wavelengths with good spatial resolution to obtain a large promising sample of massive stars. In recent years, Galactic mid-infrared bubbles around the expanding HII regions have received much attention, because of their ability to triggering new generations of star formation including massive star(s). It is now believed that such regions are very promising to investigate the physical mechanisms, which govern the interaction and feedback of massive stars on their surrounding environment. In this talk, I will present the results related to our ongoing work on infrared bubbles, including the important of multi-wavelength approach. |
