Abstract
Pulsation models for the enigmatic F-type supergiant variable, UU Herc ulis are investigated. It is shown that irregular pulsations with smal l amplitude is realized, if UU Her is assumed to be an intermediate-ma ss-F-type supergiant star which has evolved with mass loss and rotatio nal mixing and thus highly luminous, compared with what is obtained by conventional evolution.
