SO observations towards Bok globules

The results of a survey of 30.0-GHz (JN=10−01) SO emission towards 21 Bok globules associated with an IRAS counterpart are presented. Fully sampled SO maps of the region around the IRAS coordinates have been obtained. We found SO emission in 13 (62 per cent) Bok globules and, for three of them, we h...

Description
Summary:The results of a survey of 30.0-GHz (JN=10−01) SO emission towards 21 Bok globules associated with an IRAS counterpart are presented. Fully sampled SO maps of the region around the IRAS coordinates have been obtained. We found SO emission in 13 (62 per cent) Bok globules and, for three of them, we have mapped the whole SO structures, which have elongated shapes and contain clumps in their interior. The SO cloud sizes range from 0.20 to 1.13 pc, while the derived total SO column densities at the position of the SO peaks are between 0.6 × 1013 and 4.5 × 1013 cm−13.
