Abstract

Up to now, the period-doubling bifurcation in variable star is identified through the existence of subharmonics in the power spectrum of light curves. Therefore the question is arisen: How to find a general criterion of period-doubling bifurcation in pulsating stars from theoretical analysis. It isdiscussed in this paper. We found that for the stellar pulsating mapping the bifurcation from a fixed point to a two-cycle occurs at parameter lambda(1) = -0.63, i.e., adiabatic exponent Gamma(1) = 1.331.
