Classical Pulsators: Contrast Between Pulsation Modes

Classical Pulsators: Contrast Between Pulsation Modes

Radosław Smolec

We comment on the differences between classical pulsators, Cepheids and RR Lyrae stars, in which the dominant variability is due to radial fundamental mode and due to radial first overtone mode. We consider the occurrence of periodic modulations of pulsation, excitation of additional low-amplitude periodicities and overall stability of the stars pulsating in the two radial modes.
