The Nature of a Twelve-Year Periodicity in the Symbiotic Nova RT Ser
Abstract
The 12 yr orbital period of the symbiotic nova RT Ser is confirmed from wave-like brightness variations and changes in the H_alpha emission line profile. We explain these variations in terms of a reflection effect arising in the photosphere of a red giant.
