Description
A theoretical analysis is done to explore the dynamics of nonlinear gravito-electrostatic wave in the molecular clouds. It contains warm lighter electrons, ions and massive positively and negatively charged dust grains. The effects of multi-fluidic viscous drag forces, the gradient forces, naturalistic equilibrium inhomogeneities and nonlinear convective dynamics are also considered. A couple of inhomogeneous Korteweg de-Vries Burger (i-KdVB) equations are analytically derived using a multiscale approach [1-3]. To investigate the fluctuations dynamics of the gravito-electrostatic wave, a numerical method is carried out []. In the numerical treatment it is seen that the waves propagate as electrostatic rarefactive damped oscillatory shock-like structures and self-gravitational compressive damped oscillatory shock-like structures. The applications and implications in the diverse astro-media of these fluctuations are also enlighted.
