OBSERVATION OF BOWEN FLUORESCENCE AND OTHER PHENOMENA IN FIVE SYMBIOTIC STARS

Wavelength measurements and line identifications in the 3200 Å-3600 Å region are presented for AG Dra, HM Sge, V1016 Cyg, V1329 Cyg, Z And, and R Aqr. Except for R Aqr all of the systems showed high levels of ionization as exemplified by the presence of [Ne í] and [Fe vii]. The O iii lines that are...
