Pulsation timescales and amplitudes in a sample of bright semi-regular variable stars.

Abstract (from CDS):
We have analyzed the differential V-band photometric variations of records up to 8 years long in ten M III semi-regular (SR) variable stars. Periodograms constructed from each star's entire record and seasoned intervals were used to find repetitive occurrences of pulsation periods in the range of 10 to 250 days. For every star at least one locus of periods was observed, with many stars showing two distinct distributions of pulsation timescales.
The observed pulsation periods and differential V-magnitude semi-amplitudes appear to be correlated such that longer periods correspond to larger semi-amplitudes.
