| Abstract: |
The dust formed in extended circumstellar envelopes of long-period
variables and Miras has a strong influence on the envelope dynamics.
A radiatively driven instability caused by the formation of dust leads
to the development of autonomous dynamics characterised by a set
of distinct frequencies. We study the interplay between the envelope's
internal dynamics and an external excitation by a pulsating star. |
