Scientific paper

The dispersion equation for radial, axial and azimuthal instabilities of an isothermal disc with a three-dimensional magnetic field is derived by the perturbation method. The effects of the different field components are discussed in detail. The authors find that the radial and azimuthal fields Br, Bφ are mainly responsible for enhancing the instability of the magneto-acoustic modes and non-axisymmetric modes, and that pulsational oscillations are larger in the radial than in the Z direction. The model may be useful in explaining the periodic light variations of FU Orionis and T Tauri stars.
