  • 摘要:The structures of the protoplanetary disk have been examined under various conditions of the stellar wind and the mass distribution of the disk, by assuming that the disk is steady and geometrically thick.T Tauri stars are commonly accompanied by disks as well as the stellar wind.Therefore, the disk around a T Tauri star should be influenced by the stellar wind.The height of the geometrical surface of the disk is suppressed by the dynamical pressure of the wind but depends very weakly on the wind strength.The surface becomes slightly higher when the wind strength becomes weaker.Furthermore, the dependency on the mass distribution of the disk is also weak.As a natural result, the temperature distribution in the disk is insensitive to the wind strength and also the mass distribution of the disk.Thus, we can conclude that the temperature and the geometrical surface height of the disk under the stellar wind does not depend on either the wind properties or the mass distribution of the disk. Key words Passive disk mass loss rate stellar wind mass distribution.
