Astronomische Gesellschaft Abstract Series, Vol. 17., (2000)
Abstract:
Miras and long-period variables (LPVs) are highly evolved, pulsating stars on the Asymptotic Giant Branch (AGB) with massive outflows and prominent circumstellar dust shells (CDSs). A CDS, driven by the stellar pulsation, can be considered as a dynamical system which reveals various kinds of complex phenomena like spatio-temporal instabilities, bifurcations, multiperiodicity and transition to chaos.
