Globules and pillars in Cygnus X

IRAS 20319+3958 in Cygnus X South is a rare example of free-floating globule (mass ~240 Msun, length ~1.5 pc) with an internal HII region created by the stellar feedback embedded intermediate-mass stars, particular, one Herbig Be star. Here, we present Herschel/HIFI CII 158 mu map whole and large set other FIR lines (mid-to high-J CO observed Herschel/PACS SPIRE, OI 63 line 16-15 upGREAT on SOFIA), covering head partly position tail. The revealed that probably rotating. Highly collimated, high-velocity emission detected close to We performed PDR analysis using KOSMA-tau code for can be reproduced two-component model: extended, non-clumpy outer shell clumpy, dense, thin inner layer, representing interface between cavity external PDR. modelled UV field ~2500 Go similar what obtained from Herschel fluxes, but lower than estimated census stars. External illumination ~30 pc distant Cyg OB2 cluster, producing ~150-600 G0 as upper limit, responsible most emission. For tail, component, exposed UV-field around 140 Go.
