The Gravitational Stability of Rotating streaming fluid medium pervaded by general magnetic field

Abstract

The stability of a homogeneous fluid medium has been investigated by Jeans (1902). Chandrasekhar (1981) made several extensions. Recently Radwan (2001) developed the Magnetogravitational stability of fluid medium. In these work, we study the Gravitational stability of rotating streaming fluid medium pervaded by general magnetic field . We found the streaming is destabilizing. The electromagnetic force has strong stabilizing effect the present model but the rotating forces are destabilizing according to restrictions. The selfgravitating force is stabilizing or not according to restrictions. The selfgravitating Jean's instability criterion is not affected by the influences of the different parameters of the problem specifically by the rotation. This work has many application in Applied Physics.
