英文摘要 | 3C 397 is a radio and X-ray bright Galactic supernova remnant (SNR) with an unusual rectangular morphology. Our CO observation obtained with the Purple Mountain Observatory at Delingha, Qinghai Province, China reveals that the remnant is well confined in a cavity of molecular gas and embedded at the edge of a molecular cloud (MC) at the local standard of rest systemic velocity of similar to 32 km s(-1). The cloud has a column density gradient increasing from southeast to northwest, perpendicular to the Galactic plane, in agreement with the elongation direction of the remnant. This systemic velocity places the cloud and SNR 3C 397 at a kinematic distance of similar to 10.3 kpc. The derived mean molecular density (similar to 10-30 cm(-3)) explains the high volume emission measure of the X-ray emitting gas. A (12)CO line broadening of the similar to 32 km s(-1) component is detected at the westmost boundary of the remnant, which provides direct evidence of the SNR MC interaction and suggests multi-component gas there with dense (similar to 10(4) cm(-3)) molecular clumps. We confirm the previous detection of an MC at similar to 38 km s(-1) to the west and south of the SNR and argue, based on H I self-absorption, that the cloud is located in the foreground of the remnant. A list of Galactic SNRs presently known and suggested to be in physical contact with environmental MCs is appended in this paper. |
