Studies of symbiotic stars. II. V1016 CYG : a binary of 6.0 yr period with variable dust obscuration.
Abstract
On the basis of an incomplete portion of an UV light curve, it has been recently suggested that the very slow nova V1016 Cyg is a binary system with a 9.5 year orbital period. Following the analysis of a two decade long IR photometry, the author proposes a different orbital period, namely 6.0 years. This determination originates from modelling the dust obscuration episodes experienced by the Mira variable in V1016 Cyg. The Mira has a pulsation period of 478 days and very probably fills its Roche lobe. A temperature of 800K is derived for the dust around the Mira.
