New radial systems of dark globules
We present the results of a systematic survey of ESO/SRC plates of the Southern Hemisphere aimed at discovering new radial systems of dark globules. During this survey, we found 16 new type 1 radial systems and 6 type 2 radial systems. We thus doubled the number of known radial systems. O-B2 type stars are situated at the centers of type 1 radial systems, but there are no early-type stars in the centers of type 2 radial systems. An attempt was done to provide an interpretation of the groups of starless condensations as radial systems of dark globules situated behind thick dark clouds, which would explain why these globules are seen only at submillimeter wavelengths.
