A class of solutions of Einstein field equations satisfying Karmarkar embedding condition is
presented which could describe static, spherical fluid configurations, and could serve as …

The current paper presents a double-layered neutral anisotropic stellar model in general
relativistic setting. The model is developed by using Einstein field equations and class I …

In this paper, we explore a new parametric class of exact solutions of the Einstein field
equations (EFEs) under the Karmarkar condition for anisotropic fluids. The solutions are …

Starting from the known condition of Karmarkar, which guarantees that a static and
spherically symmetrical space-time is embedded in a manifold of dimension 5, and that it …
