A generalized Finch-Skea class one static solution
Abstract
In the present article, we discuss relativistic anisotropic solutions of the Einstein field equation for the spherically symmetric line element under the class I condition. To do so we apply the embedding class one technique using Eisland condition. Within this approach, one arrives at a particular differential equation that links the two metric components and . In order to obtain the full space-time description inside the stellar configuration we ansatz the generalized form of metric component corresponding to the Finch-Skea solution. Once the space-time geometry is specified we obtain the complete thermodynamic description i.e. the matter density , the radial, and tangential pressures and , respectively. Graphical analysis shows that the obtained model respects the physical and mathematical requirements that all ultra-high dense collapsed structures must obey. The diagram suggests that the solution yields stiffer EoS as parameter increases. The graph is in agreement with the concepts of Bejgar et al. \cite{bej} that the mass at is lesser by few percent (for this solution ) from . This suggests that the EoSs is without any strong high-density softening due to hyperonization or phase transition to an exotic state.
