Research Interest

Multi-wavelength observational and theoretical study of star formation Star formation and early stellar evolution is one of the hottest topics in modern astrophysical research fields. To understand star formation is the basis of understanding of planet and galaxy formation. Star formation process is extremely complex, which includes a lot of physical process such as collape, accretion, outflow, shock wave, collision and so on. Besides the self-collape of molecular clouds,the external trigger mechanism could play a key role for next generation of star formation. Our present project is focusing on the study of trigger star formation by molecular clouds collision and the interaction between HII regions /bubble or SNRs and the surrounding molecular clouds. We will try to obtain a large sample of candidates of possible clouds collision and the molecular clouds associated with HII regions and high-mass stars, on the basis of CO molecular line survey and other observational data on different wavelenghs, and to make millimeter, submillimeter, radio, optical and infrared observations. Then we will try to diagnose the external trigger condition and mechanism of star formation, and to build theoretical models. Our results will be helpful for understanding the trigger mechanism and process of Galactic star formation. It also can provide  with very important evidence of the process of Galactic evolution.
