Abstract
Several problems of the theory of the RV Tauri stars are reviewed on the basis of the numerical nonlinear modelling. We analyse the nature of the alternating pulsations of these variables, and discuss their relation to the period doubling phenomenon in W Virginis stars. We also discuss the period-luminosity relation for RV Tauri stars, recently obtained following the MACHO survey of the LMC stars, and compare it to the theoretical prediction. The problem of the secondary long-period variability of the RVb group is analysed in the frame of the binary nature of these stars.
