An Oscillator Model for Stellar Variability
Abstract
The dependence of coupling constants in a coupled oscillator model is examined with simplified methods. The Lyapunov exponents are preliminary introduced for the model. The behaviors of oscillator model are examined in a parameter plane. So-called the Arnold's tongues for phase-locking states are observed in fractal patterns.
