Is the model of one-armed oscillations able to explain the long-term V/R changes of Be stars?

Abstract

We carried out detailed tests of the dependence of V/R 'periods' predicted by the model on all individual input parameters. We arrived at the following results: (1) the model has great potential to explain not only the cause of the cyclic long-term V/R changes but also some of the observed statistical properties of the phenomenon. (2) The model in its present linear form cannot be considered as proven.
