Anisotropic Strange Stars in the Spotlight: Unveiling Constraints through Observational Data

Abstract

Motivated by the recent suggestions that very massive and very light compact objects exist, in this letter we revisit the possibility of such objects being strange stars instead of the standard hadronic neutron stars. We study the possible presence of local anisotropy and how it affects the macroscopic properties of strange stars and compare our results with the recent constraints presented in the literature. We found that the presence of anisotropy increases the maximum mass, the radius of the canonical star, and its tidal deformability for positive values of $\lambda_{\rm BL}$, and the opposite for negative values. We also show that some observational constraints that are in conflict with the theory of standard hadronic neutron stars, can easily be taken into account considering strange stars.Comment: 5 pages, 2 figures, 1 table, comments are welcom
