摘要：

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 Carl 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 5 arcsec from a Tr = 12.8 G companion. We suggest it to be a yellow symbiotic star.
