AbstractThe stability of an isothermal magnetized accretion disk is examined both analytically and numerically. We find that acoustic instabilities exist not only in purely viscous disks, but also in disks where viscosity and magnetic field coexist. The inclusion of magnetic field does not change the local stability properties very much, apart from altering the numerical values of the growth rates. If the growth rate is required to be greater than the escape rate, the acoustic modes are unstable only in the long wavelength limit and when some viscosity and magnetic field parameters are larger than certain values. These results are unchanged if a different viscosity prescription is adopted.
