Abstract (from CDS):

Result. of first CCD photometry during the recent deep light decline, and high-resolution spectroscopy, are presented for DY Persei. The spectra show variable blueshifted features in the sodium D lines. The Ci lines are strong whereas neutron-capture elements are not enhanced. The isotopic 13CN(2,0) lines relative to 12CN are of similar strength with those for the carbon star U Hya. All these confirm the RCB nature of DY Per and the existence of ejected clouds. At least two clouds are revealed at -197.3 and -143.0km/s. A star was detected about 0.4" to the west and 2.5" to the north from DY Per. This anonymous companion, with observed colour indices (B-V)=0.68 and (V-R)≃1.1, may be a foreground star.
