This 1998 research paper by G. I. Ogilvie from the University of Cambridge investigates the theory of waves and instabilities in differentially rotating accretion discs containing poloidal magnetic fields using ideal magnetohydrodynamics. The study classifies various wave modes, identifies the stability boundaries for the magnetorotational instability in thin discs, and demonstrates that stable equilibria exist which are capable of launching centrifugally driven winds.
