Abstract
In the present work, the role of rotation with viscous tensor in anisotropic self-gravitating plasma has been investigated using magnetohydrodynamic (MHD) model and Chew-Goldberger-Low (CGL) fluid theory. The general dispersion relation is obtained by normal mode analysis theory with the help of linearized perturbation equations and further discussed with some limiting cases. The modified condition for Jeans instability has been obtained. The influence of considered parameters on the growth rate of instability is shown analytically and numerically. The result of present study may be useful in the region of spiral arms of galaxy.
