Abstract:

The dispersion relation for gravitational instability is derived within the framework of a two-fluid theory. It is shown that the Jeans criterion is changed by finite Larmor radius effects and by collisions for wave propagating perpendicular to the magnetic field. The critical wavenumber for instability decreases with increasing Alfven velocity and with increasing gyroviscosity. Instability does not set in with overstability. Author
