Scientific paper

An attempt is made to give evidence of interesting properties of pulsating stars, which are not related to amplitude ratios but which can be derived from the study of the relations among the amplitudes. A comparison of the Fourier amplitudes of RR Lyrae and high amplitude Delta Scuti and SX Phe star light curves shows some similarities between the two types of variable stars. In particular, Delta Scuti stars are separated into two groups, in a manner similar to the groups of RRab and RRc stars.
