VizieR Online Data Catalog: Globules and pillars in Cygnus X (Schneider+, 2021)
Abstract
We present submm-FIR observations with Herschel and SOFIA of the globule IRAS 20319+3958 in Cygnus X South. It contains an internal HII region created by the stellar feedback of embedded intermediate-mass stars, in particular one Herbig Be star. The CII map revealed that the whole globule is probably rotating. Highly collimated, high-velocity CII emission is detected close to the Herbig Be star. We performed a PDR analysis using the KOSMA-tau PDR code for one position in the head and one in the tail. The observed FIR lines in the head can be reproduced with a two-component model: an extended, non-clumpy outer PDR shell and a clumpy, dense and thin inner PDR layer, representing the interface between the HII region cavity and the external PDR. External illumination from the 30pc distant Cyg OB2 cluster is responsible for most of the CII emission.
