摘要
New observations of the HI 21 cm line toward the cometary HIT region G213.880-11.837 are presented. These observations, carried out with an angular resolution of similar to 15 '', reveal that the neutral gas in this region is part of an expanding flow. The analysis of the kinematics of the HI gas suggests that the HI gas is undergoing a champagne flow: based on the difference between the radial velocities of the neutral gas in the tail (similar to 14 km s(-1)) compared to the velocities of the ambient molecular gas (similar to 11.5 km s(-1)) and the asymmetry of the HI emission. Besides this photodissociated region, there is only one other reported following an HI champagne flow (G111.61+0.37).
