Imaging polarimetry of some selected dark clouds

A set of eight Bok Globules CB3; CB25, CB39, CB52, CB54, CB58, CB62 and CB2 46 were observed polarimetrically in white light: using our Imaging Polarim cter (IMPOL), from the 1.2 m IR telescope at Mount Abu: India. The observat ions were carried out on different nights during the period December 1997 a nd April 1998. The CCD images obtained from the instrument (IMPOL) were ana lyzed, to produce polarization map of the Bok Globules. The stars in the fi eld: which are mostly background to the cloud show typically 2% of linear p olarization. Clouds which are less dynamic (having (CO)-C-12 line widths De lta V < 2.5 km s(-1)), in general show slightly better alignment of polariz ation vectors with the projected direction of galactic plane. On the other hand the more dynamic group of clouds, has the polarization vectors more sc attered and poorly aligned with the projected direction of the galactic pla ne. However one of the clouds observed CB58 does not follow this trend very well.
