The behavior of the symbiotic nova RT Ser from 1940 to 1994 from photographic observations made at the Gissar Observatory (1940–1978) and BVR-band observations at the Crimean Observatory (1983–1994) is analyzed. The outburst lightcurve shows a linear decline at a rate of 0m.06 per year. It appears from the nature of the outburst attenuation that the fading, having already lasted about 80 yr, is still continuing. Judging from the color indices, the principal contribution to the visible light… Expand

Symbiotic novae occur in double star systems, where mass lost by a red giant is accumulated by wind accretion onto a white dwarf. When a critical mass has been reached, a novalike outburst of longExpand
