04510, e-mail: gelover@unam.mx Received 30 April 2015; accepted 13 October 2015 A model for the adiabatical pulsation of a Cepheid based on primary physical principles such as energy conservation, mechanical adiabaticity and hydrostatic equilibrium is presented.
The adiabatical treatment of the pulsation has been already studied by other authors but the novelty of our model is that it allows to obtain physical parameters of the star, namely the amplitude of the oscillation, the mass, maximal velocity of the pulsation and luminosity. Keywords: Geophysics; astronomy and astrophysics; stars; variable; peculiar stars; cepheids. PACS: 97.30.-d; 97.30.Gj 1.
