Relativistic models for anisotropic compact stars: A review

J Kumar, P Bharti - New Astronomy Reviews, 2022 - Elsevier
Abstract The Einstein–Maxwell (or Einstein) system of field equations plays a substantial
role in the modeling of compact stars. Although due to its non-linearity getting an exact …

Anisotropic neutron stars modelling: constraints in Krori–Barua spacetime

Z Roupas, GGL Nashed - The European Physical Journal C, 2020 - Springer
Dense nuclear matter is expected to be anisotropic due to effects such as solidification,
superfluidity, strong magnetic fields, hyperons, pion-condensation. Therefore an anisotropic …
