Nonlinear Pulsations of Convective Stellar Models
J. Robert Buchler
We review the numerical modelling of the nonlinear pulsations of classical variable stars with hydrocodes that include the effects of turbulent convection. Despite their simplicity…
Turbulent Convection in Pulsating Stars
J. Robert Buchler, Philip Yecko, Zoltan Kollath +1
We review recent results of stellar pulsation modelling that show that even very simple one-dimensional models for time dependent turbulent energy diffusion and convection provide…
Modelling the Phase-Locked Pulsations of a P=14d EROS Star
Z. Kollath, J. R. Buchler, J. P. Beaulieu +1
The Fourier spectral analysis of this object suggests a nonlinear pulsation of period approximately 14d with a 3:2 frequency lock between two vibrational modes. We discuss an exten…
Classical Cepheids -- a Review
J. Robert Buchler
We briefly review the evolutionary status of the classical Cepheid variables, their structure, and the properties of the linear modes. Then we discuss the current status of the non…
