Line-integrated [C II] 158 μm emission of the globule obtained with HIFI on Herschel in the velocity range 0–15 km s⁻¹. The blacktriangle indicates the double system (Star A) of which at least one is a Herbig Be star, the white rectangle points to Star B with a B0.5 - B1.5 spectral type, and the black cross marks Star C, a resolved binary of which one is a late O or early B star. The centre position (0,0) is at RA(2000) = 20^h33^m49.95, Dec(2000) = 40°07′42.75″. The [C II] beam is indicated in the lower left corner. The dashed lines indicate the vertical (north-south) cuts where we performed position-velocity maps and the dark grey circles mark the positions and the extend of the SPIRE beam for the longest wavelengths (FWHM ~ 40″) we used for PDR modelling. The position in the north is the globule ‘head’ and the one in the south the globule ‘tail’.
