Collapsing of charged cylindrical symmetric source in f(R, G) gravity with heat flux

This investigation deals with the dynamics of charged cylindrical gravitational collapse with anisotropic pressure and heat flux in f(R, G) gravity. For this purpose, we adopt the Misner-Sharp formalism to construct the dynamical equations and derive transport equation. Furthermore, we examine the collapsing rate by coupling the transport and dynamical equations. It is observed that the higher-order curvature terms influence the whole collapsing process such that the presence of positive curvature terms speeds up the collapsing process. It is also noted that for constant f(R, G) model the collapsing rate reduces.
