| 英文摘要 | We present our (12)CO and (13)CO mapping observations of SNR IC 443 interacting with molecular clouds. It is the first large-scale high-resolution (13)CO mapping observation in the surrounding region. The morphologies of IC 443 in (12)CO and (13)CO are compared with the optical, infrared, Spitzer far-infrared, X-ray, and neutral atomic gas (HI). We also make comparison and analysis in the kinematics, using the date-cubes of (12)CO, (13)CO and HI, to help distinguish the complicated gas motions in the shocked regions. Based on the work of Wang & Scoville (1992), we present a new model to explain the coexistence of multiple shocks with different speeds in a pc-scale region at the central clump B. We test this new model by analyzing the HI and CO distribution in both velocity and space domain. We also establish the relationship between the dissociation rate of shocked molecular gas and the shock velocity in this region. Finally, we derive the optical depth of (12)CO with the (13)CO spectra in clump B, and discuss the validity of the assumption of optically thin emission for the shocked (12)CO. |
