Ruprecht 55: An OB association at the edge of our Galaxy

We present new spectroscopy in the optical range and 21-cm Hi data covering the Ruprecht 55 (Ru 55) field in the Puppis window where several authors have proposed the existence of one (or two) clusters. We have determined new MK spectral types for about 50 stars in the region, finding 43 OB-type sta...
