We conducted a survey for radial velocity variability in search of binary systems, which are expected to be plentiful in young OB associations. Here we report the discovery of two new single-lined binaries, and we present new orbital elements for three double-lined binaries (including one in the multiple star system HD 17505). One of the double-lined systems is the eclipsing binary system DN Cas, and we present a preliminary light curve analysis that yields the system inclination, masses","authors_text":"David W.
