摘要：

A simple model is proposed to explain the ~ 3-hr periodic variations seen in the radiation from Nova Cygni 1975. The underlying binary system creates a spiral density variation in the outflowing wind. Such a spiral may persist to large radii and is then observable where it intersects the scatter-sphere. Period changes in the observed magnitude variations can naturally occur, without any change in the underlying binary period. © 1977 Royal Astronomical Society.
