| Abstract: | Some corrections and improvements to the beat frequency model for the quasi-periodic oscillation phenomenon in X-rays binaries have been made in this paper. The main point is that the viscous damping in the column accretion process has been taken into consideration, which successfully accounts for the two-branch spectrum behaviour unexplained by the previous beat frequency model. |
