Özet

A model of 5 M⊙ hydrogen-helium star with no metals has been considered. The properties of the adiabatic oscillations were obtained, and the vibrational instability of the model has been investigated. The model is a double-shell burning star. Calculations were done for the fundamental mode as well as the first and the second harmonics. The model has been found vibrationally unstable against radial adiabatic pulsations. © 1990 Kluwer Academic Publishers.
