Period changes in RV Tauri stars: observations and simulations.

PERCY J.R., CSATARY A. and ZORGDRAGER I.

Abstract (from CDS):

We have determined the times and magnitudes of minimum brightness of two RV Tauri stars (SS Gem and V Vul) using data from the AAVSO and from the literature. We have used these to construct (O-C) diagrams. These are dominated by cyclic features with time scales ranging from several to several hundred pulsation periods. By constructing simulated (O-C) diagrams, we have shown that the observed (O-C) diagrams could be explained by the accumulation of random, cycle-to-cycle fluctuations in period, as in the case of most Mira stars.
