Amplitude variations in the delta Scuti variable Theta-2 Tauri.

ZHIPING L., AIYING Z. and DAWEI Y.

Abstract (from CDS):

We obtained 413 Johnson V obsrevations of theta-2 Tau during nine nights of photoelectic photometric measurements. The Period analysis of the new data confirms the five-frequency solution found be Breger et al. in 1989. However, the new data show that the pulsation modes have experienced amplitude redistribution, on a time scale estimated to be ten years. The variations are in good agreement with predictions of resonant mode-coupling theory.
