概要

• 論文の詳細を見る

• The two-mode coupling in hydrodynamic models of classical cepheids is investigated. The centre of resonance is situated at the period ratio P_<2O>/P_F=0.49 for a model sequence having 5091 L_⊙ and 5 M_⊙. The phase of bump of the luminosity- and photospheric velocity-curves coincides with the analytical results of two-mode resonance theory. The decrease of amplitude at the resonance centre is also found in the model sequence.Stellar pulsationHydrodynamic modelResonance
