内容記述 | Performed are numerical simulations of the radial circulation of dust particles in weak turbulent protoplanetary disks, taking the effect of radiation pressure of the central star and puffed-up inner rim of the disk into account. It is confirmed that the following dust circulation mechanism will be realized: at the inner edge of the disk, infalling dust aggregates partially evaporate and break up into fine grains, which are stirred up to the upper irradiated region by convection and are blown outward by the radiation pressure. Most of the blowing grains reenter into the disk within about 1 AU and settle to the midplane, joining inwardly-migrating dust aggregates. It is found that in the inner disk the outflow mass flux in the surface layer is comparable to the inflow mass flux in the disk interior, if the intensity of gas convection at the inner edge is efficient enough and stellar luminosity is 1.5 times brighter than the present Sun. | |||||
