英文摘要	We make a systematic calculation of the spectra and hadronic decays of the D-s system in a coupled channel framework, where the unquenched effects are induced by the P-3(0) model. In the calculation, the wave functions are obtained by using a nonrelativistic potential model and are handled precisely with Gaussian expansion method. Even though the fitting mainly focuses on the spectrum, our model agrees well with the experiments on both the spectra and the hadronic decays, suggesting that the coupled channel effect could result in a reasonable and coherent description of the D-s mesons. Based on the calculation, we give a detailed analysis on various aspects of the excited states, especially D-s0*(2317), D-s1(2460), D-s1(2536), D-s1*(2860), D-s0(2590), and D-sJ*(3040). We also predict that D-s(0)*(2(3)P(0)) should be a D*K* dominant molecule with mass 2894 MeV, which is only 5 MeV below the D*K* threshold.
