A SPECTRUM OF THE SYMBIOTIC NOVA RT SERPENTIS

The spectrum of RT Ser (Nova Serpentis 1909) was observed in 1979 in the range 6300 Á to 6750 Á, at a resolution of 0.6 Å. In addition to the dominant Ha line, weak emission lines of [O i] λ6363 and He I λ6678 were detected. These lines have radial velocities of 64, 82, and 77 km s⁻¹, respectively....

Zusammenfassung:	The spectrum of RT Ser (Nova Serpentis 1909) was observed in 1979 in the range 6300 Á to 6750 Á, at a resolution of 0.6 Å. In addition to the dominant Ha line, weak emission lines of [O i] λ6363 and He I λ6678 were detected. These lines have radial velocities of 64, 82, and 77 km s⁻¹, respectively. Emitting regions with different physical conditions around RT Ser appear to have different radial velocities.
