Bok globule CB17: Polarization, extinction and distance
G. B. Choudhury, A. Barman, H. S. Das +1
In this paper, the results obtained from the polarimetric study of a Bok globule CB17 in both optical and sub-millimeter wavelength are presented. The optical polarimetric observat…
Magnetic field geometry of the large globule CB 34
A. Das, H. S. Das, Biman J. Medhi +1
We report the results of optical polarimetric observations of a Bok globule CB34 to study magnetic field structure on large scales ( AU), which is combined with archival…
Study of magnetic field geometry and extinction in Bok globule CB130
A. Chakraborty, H. S. Das
We trace the peripheral magnetic field structure of Bok globule CB130, by estimating the linear polarization of its field stars in the R band. The magnetic field orientation sample…
Distance estimation of some selected small Bok globules
A. Das, H. S. Das, A. S. Devi
The distance determination of small Bok globules is often difficult because of its small size and opaqueness. In this work, we determine the distances to six small Bok globules CB…
Study of grain alignment efficiency and a distance estimate for small globule CB4
Ajoy Barman, Himadri Sekhar Das
We study the polarization efficiency (defined as the ratio of polarization to extinction) of stars in the background of the small, nearly spherical and isolated Bok globule CB4 to…
Study of background star polarization and polarization efficiency of three selected Bok globules CB56, CB60 and CB69
A. Chakraborty, H. S. Das, D. Paul
We present the polarization maps of three selected Bok globules CB56, CB60 and CB69 constructed using a V-band data from a CCD imaging polarimeter. The aim of this work is to measu…
Large-scale magnetic fields in Bok globules
Gesa Bertrang, Sebastian Wolf, Himadri S. Das
Context: The role of magnetic fields in the star formation process is a contentious matter of debate. In particular, no clear observational proof exists of a general influence by m…
