Proper-motion survey. I - Common-proper-motion systems in ESO areas 439 and 440
Abstract
Spectra and BVRI CCD photometry of stars members of 15 common-proper-motion systems, found in red ESO Schmidt plates (areas 439 and 440) were used to derive their spectral types and distances. The sample contains two emission-line red dwarfs, one double degenerate pair, and three systems with one degenerate component, one of which is a spectroscopic binary.
