Abstract
A very general approach to hydromagnetic instability in a magnetospheric geometry is given. The specific effects of the presence of finite ..beta.. ring current particles and cold particles of ionospheric origin are included. The generality of approach allows the theory to interrelate various approaches to low-frequency stability. It is concluded that resonant particle instabilities are likely to be the source of low-frequency oscillations that have been observed. Instability conditions and growth rates are estimated. Alfven waves may be excited with ..beta..<1, while for ..beta..approximately-greater-than1, compressional disturbances are expected to be generated. (AIP)
