Photometric and spectroscopic study in the region of Ruprecht 44 and the Galaxy structure
Abstract
We carried out an extended photometric survey in the region of the open cluster Ruprecht 44 combined with spectral types of some bright stars in the area. Preliminary results suggest the presence of two stellar populations superposed along the line of sight: one is the open cluster itself placed at almost 6 kpc while the other is a dispersed blue population extending outwards the Galaxy up to over 14 kpc. The stellar distribution and cluster distance confirm earlier findings of our group.
