Thermodynamic stability and fluid behavior in charged Hayward black hole

Three different viable extensions of the regular Hayward black hole are developed in this paper in the presence of electric charge. In this regard, a well-known technique labeled as the gravitational decoupling is taken into account which is mostly used to generalize the domain of the existing solutions. Initially, the anisotropic fluid is considered in the interior of a static sphere which is then extended by adding the another fluid Lagrangian. The field equations now contain the effects of both sources and thus admit multiple unknowns, making them much complicated. We then separate these equations into two different systems by applying the minimal geometric deformation approach. The solution to first of them is figured out through the consideration of charged Hayward black hole, whereas some particular constraints are used to tackle with the other system. Afterwards, construction of a linear combination of both these solutions provides the required extensions. Furthermore, a detailed graphical analysis is performed on the behavior of fluid parameters and energy conditions. Finally, we perform the stability analysis through the investigation of thermodynamic properties and deduce that all the developed solutions show stable behavior in a particular region for the chosen parametric values.
