Dissipative Cylindrical Collapse of a Charged Anisotropic Fluid in Gravity
arXiv:1707.03666 · doi:10.1139/cjp-2017-0104
Abstract
This paper is devoted to investigate the cylindrical collapse of an anisotropic fluid in gravity. For this purpose, the viscous charged anisotropic fluid dissipating energy with heat flow and shear is assumed. We use the perturbation scheme to develop the dynamical equations for the variables that ultimately lead to the disturbance of the physical variables and the Starobinksy like model chosen. The evolution of the matter variables is discussed with the help of these equations. It can be concluded that the range of dynamic instabilities depends on the field strength, density distribution, pressure and the curvature term of the model. We find that our results of Newtonian and post-Newtonian regimes reduce asymptotically to general relativity solutions in the limiting case.
