Abstract
Solar-like oscillation frequencies of 93 target stars of Kepler and CoRoT are analyzed. In the present study, we present results for two of them. Recently, two new reference frequencies nu_min1 and nu_min2 are found in the spacing of solar-like oscillation frequencies of stellar interior models. In order to fit model frequencies to observational frequencies, we change model mass and hydrogen abundance. We also try to obtain similar patterns around min1 and min2 for model and observational frequencies.
