Semiregular variables: are they chaotic or ringing ?
WHITNEY C.A.
Abstract (from CDS):
Two types of irregular behavior in semiregular variables, labeled randomness and chaos, are described and the results of recent theoretical explorations are illustrated. The need for precise long-term observations to distinguish between multi-periodic and irregular pulsations in semiregular variables is emphasized.
