F. ; Gautschy, A. ; Dickens, R. J. Abstract It is well known that type 'c' RR Lyrae stars pulsate in the first-overtone mode. These stars also show a distinctive light curve shape. It is shown, using a simple model, that this shape is indeed an expected feature of the overtone and is caused by the reversal of phase of the luminosity variation at the pulsation node, deep in the star. This result also applies to other types of radially pulsating stars and should aid in identifying overtone pulsation directly from the light-curve shape. The model is then used to predict the light variation of type 'e' (second-overtone) pulsators.
