Petrov, Registration Date 15-01-2013 Organization Scientific-research institute "Crimean astrophysical observatory" popup.description2 The life-time of accretion disks of young low-mass stars is determined as from 0.7 to 10 Myr, with rotation period of a star being constant during this phase of evolutioon. It is found that the angular momentum of a star depends on its internal structure: fully convective stars rotate slower than the stars with a radiative core, which indicates evolution of the magnetic field topology from predominantly dipole to a multipolar. Cyclic changes in structure of magnetosphere of an intermediate mass stars AB Aur is reveled. The effect is caused by diffusion of the magnetic field inside the accretion disk and subsequent generation of a disk wind. Complex structures of protoplanetary disks of young stars are reveled. In particular, an active asteroid belt with a large collision frequency is found in RZ Psc. Product Description popup.authors Антонюк К.А. Артеменко С.В. Бабіна О.В. Белан С.П. Гранкін К.М.
