Abstract
We present highly resolved spectroscopic data of HBV475 (=V1329 Cgy) in the optical region, which have been obtained during the past 10 years at the Okayama Astrophysical Observatory. We analyzed line profiles of Hα, Hγ, HeII.λ4686, [OIII] λ5007 and [FeVII] λ6086 by using Gaussian de-convolution method and investigated variation of individual components of the profiles as a function of the orbital phase. We revised the mass function obtained from orbital elements of the hot star as fh (M) ~ 1.2 M⊙. It differs considerably from previously published values, which were larger than 20 M⊙. However, our new mass function is more reasonable for a symbiotic system consisting of a red giant and a hot star, which is currently presumed to be a white dwarf.
