Abstract

The possibility of a low-order, two-mode resonance in the pulsation of LPVs is investigated by means of Fourier analysis of lightcurves, supplemented by spectral types and by kinematic population analysis based on HIPPARCOS astrometric data. The question might be positively answered.

Key words: stars: AGB – stars: oscillations – stars: variables: long-period variables

* Based on data from the HIPPARCOS astrometry satellite.
