We use wavelets to investigate period and amplitude changes in Mira and semiregular variables and found a variety of behaviours. Period and amplitude changes often go together, perhaps because changes in amplitude are causing period changes via non-linear effects.

The evolution of the Mira variable R Hydrae

The Mira variable R Hydrae is well known for its declining period, which Wood & Zarro (1981) attributed to a possible recent thermal pulse. Here we investigate the long-term period evolution,

Period and chemical evolution of SC stars

The SC and CS stars are thermal-pulsing asymptotic giant branch stars with a C/O ratio close to unity. Within this small group, the Mira variable BH Cru recently evolved from spectral type SC

The maxima of Mira are studied in order to evaluate both the frequency of one and of two consecutive bright apparitions eventually as observed by the Magi and the correlation between two following maxima is found: if a bright maximum occurs it is more probable that the following is a faint one.

A Wall of Dust around a Proto-Mira?

We present the discovery of a huge (19′ × 16′) dust ring surrounding a bright (V = 10.60) red star. The dust ring has, at D = 700 pc, a diameter of 4 pc and a central hole of ~1.5 pc across. Part of

Long-Term Behavior of Mira Ceti Maxima

We gathered the maxima of Mira Ceti (1596-2000) in order to evaluate the frequency of two consecutive bright apparitions. We did an evaluation of the correlation between two following maxima in order



Mode switching in the nearby Mira-like variable R Doradus

ABSTRA C T We discuss visual observations spanning nearly 70 years of the nearby semiregular variable R Doradus. Using wavelet analysis, we show that the star switches back and forth between two

Long-Term Changes in Mira Stars. II. A Search for Evolutionary Period Changes in Mira Stars

The (O - C) diagrams of Mira stars are dominated by the effects of random, cycle‐to‐cycle fluctuations in period. Nevertheless, it is possible to average these effects over many stars with similar

we use the wavelet implementation by Foster (1996), with the semi-amplitude and period being derived from the WWA rather than the WWZ. terms of use, available at
