Pulsation of the AGB Variable in the Symbiotic Nova PU Vulpeculae
Abstract
Analysis of the 1993-4 eclipse in the slow symbiotic nova PU Vul (4900-d binary orbital period) and 1995-9 photoelectric observations in V and R bandpasses show that the cool component of this object is pulsating AGB variable with a 215-d pulsation period. Basic properties of the components of the system are discussed.
