Abstract
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 emiss ion lines of Balmer series, HeI, HeII, [OIII], OI and Carl triplet whi le DT Ser presents a earlier spectral type with emission of Balmer lin es, HeI, HeII and [OIII]. DT Ser is a faint V = 15.4 star 5 arcsec fro m a Tr = 12.8 G companion. We suggest it to be a yellow symbiotic star .
