| contents | Standard 1D stellar evolution model has poor descriptions of the near-surface layers of stars, and this can be improved by using the atmosphere model computed from 3D hydrodynamical simulations. In this work, we validated the model inferences of the 1D-3D coupling models using 18 well-studied stars from the Kepler LEGACY Sample. We compared our estimates of the fundamental parameters determined with other six pipelines and obtained good consistency. The results indicate that the 1D-3D coupling models can be applied to characterizing solar-like stars with confidence. Our analysis showed similar pattern for the surface term in stars with effective temperature range from ~5000 K to ~6400 K, suggesting that the surface term of the 1D-3D coupling models is simpler and easier to deal with than that of models using classical atmosphere. |
