Structure of T Tauri stars may determine the final state of the planetary system formed later. Because T Tauri stars are small and distant, it is hard to observe their structure directly. Instead, it has been deduced by calculating model spectral energy distributions (SEDs) and images and by comparing them with observed data. However, anisotropic scattering by small dust particles has not been incorporated adequately a previous work, though observed data at visible and infrared wavelengths are strongly dominated by anisotropically scattered radiation. Here, it was examined to what extent the anisotropic scattering (Mie scattering) may affect SEDs and images of T Tauri stars. It was found that the anisotropic scattering effect is not negligible and it should be taken into account faithfully in the radiative equilibrium calculations of T Tauri stars. Also, it is suggested that the radiative equilibrium calculations with anisotropic scattering model can be used to estimate the inclination of and the dust sizes in the disk., 資料番号: AA0046650003}, pages = {9--12}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Radiative equilibrium calculations with anisotropic scattering for a circumstellar disk of a T Tauri star}, year = {2003} }
