Identification of DQ Serpentis and DT Serpentis as symbiotic stars.

CIESLINSKI D., STEINER J.E., ELIZALDE F. and PEREIRA M.G.

Abstract (from CDS):

Optical and near infrared spectroscopy of the stars DQ Ser and DT Ser are presented. DQ Ser shows a late-type continuum (M3-M5) with emission lines of Balmer series, HeI, HeII, [OIII], OI and CaII triplet while DT Ser presents a earlier spectral type with emission of Balmer lines, HeI, HeII and [OIII]. DT Ser is a faint V=15.4 star 5arcsec from a V=12.8 G companion. We suggest it to be a yellow symbiotic star.
