Abstract

We report on the first scientific results with the recently commissioned PUCHEROS spectrograph, mounted at the 50cm telescope of the Pontificia Universidad Catolica near Santiago, Chile. A hitherto unknown candidate Be+sdO binary was identified, omicron Pup. If confirmed, it would be the fourth member of this class. Such stars have obtained their rapid rotation through binary mass transfer and now consist of a Be star and a hot subdwarf.
