Outline of Final Research Achievements

By performing numerical simulations, we investigated inflow-outflow structure around black holes and neutron stars. We revealed the outflows are launched via the radiation forces for the electron scattering when the accretion rate of the disk is larger than the Eddington rate and for the bound-bound absorption in the case of the near-Eddington disks. We also indicated that the radiatively outflows are fragments into many gas clumps. It was found that the mass accretes onto the vicinity of the magnetic poles when the central object is the magnetized neutrons stars. Our new results can explain the outflows and luminosity variation observed in the active galactic nuclei and X-ray binaries.
