Mass functions and photometric binaries in nine open clusters

Saurabh Sharma, +7 more
- 11 Apr 2008 - 
TL;DR: In this paper, the mass functions (MFs) of nine open clusters were studied using homogeneous CCD photometric data from the 105 cm Kiso Schmidt telescope covering a 50' × 50' field.

Biman J. Medhi, +5 more
- 21 Jul 2008 - 
TL;DR: In this article, the authors present new B,V and R linear polarimetric observations for 61 starstowards the region of the young open cluster NGC 654 and find evidence for the presence of at least two layers of dust along the line of sight to the cluster.
