The effects of various dampings on the threshold of the gravitationalinstability can be deduced by numerical solutions of (26) and (27). Due to this effect, the gravitationalinstability develops gradually in the diffusion time (approximately 21.7t0 107 years). For strong magnetic field cases, we confirm that the gravitationalinstability develops gradually on a time scale characteristic of ambipolar diffusion. The critical regime is considered in which the circulations due to the centrifugal force and the vertical gravitationalinstability are of equal significance. However, the growth rate of a possible gravitationalinstability will be reduced when collisions between ions and neutral particles are more frequent. In recent years a large number of investigators have devoted their efforts to the study of gravitationalinstability of an anisotropicpressure plasma. In this case no unstable modes could be found, which provides evidence that the mechanism triggering the breakdown of the front into the lobe-and-cleft pattern is indeed a gravitationalinstability. Mattei (1978) studied the gravitationalinstability of anisotropic plasma using polytropic relations. Alternatively, planetesimals can form in a very dense layer of dust grains that undergoes a collective gravitationalinstability in the mid-plane of a protoplanetary disk.

Planetary formation can also be triggered by gravitationalinstability within the disk itself, which leads to its fragmentation into clumps.

He has made discoveries related to gravitationalinstability in the interstellar medium and several contributions to the theory of thermal processes in magnetized dilute plasmas.

The gravitationalinstability of mature oceanic lithosphere has the effect that at subduction zones, oceanic lithosphere invariably sinks underneath the overriding lithosphere, which can be oceanic or continental.
