In the overshoot mixing model with an exponentially decreasing diffusioncoefficient, the initial value of the diffusion coefficient plays a crucialrole. According to the turbulent convective mixing model, the characteristiclength of convection in the convection zone differs from that in the overshootregion, resulting in a rapid decrease of the diffusion coefficient near theconvective boundary. To investigate this quick decrease, we conducted anasteroseismic study on the intermediate-mass SPB star KIC 10526294. Wegenerated stellar models with varied input parameters, including the overshootparameters, and compared the resulting stellar oscillation periods withobservations. To mitigate the potential issue arising from large steps in thestellar parameters and stellar age, we employed a comprehensive interpolationscheme for the stellar oscillatory frequencies, considering all stellarparameters and stellar age. Our analysis revealed that the quick decreasing ofthe diffusion coefficient has discernible effects on the stellar oscillationsand a quick decrease with 4 magnitude orders shows the best oscillatoryfrequencies compared with the observations. This provides weak evidence insupport of the prediction made by the turbulent convective mixing model.Furthermore, we examined the residuals of the oscillation periods anddiscovered a potential association between abundance anomalies in the buoyancyfrequency profile and the oscillation-like patterns observed in the residuals.
