Scientific paper

The aim of this paper is to investigate a behavior of the magnetorotational instability (MRI) in stratified accretion disks with the non-zero plasma resistivity. The flow is influenced by ohmic dissipation. A local axisymmetric perturbation analysis of the MRI in a partially ionized rotating plasma flow is presented. The limit cases of the dispersion relation are analysed. It is revealed that if the plasma has the non-zero resistivity, the convection-dominated unstable mode can survive at short wavelengths. The rΦ component of the stress tensor and the behavior of the angular momentum transport is studied numerically. Finally, the main results are summarized.
