Study of anisotropic compact stars by exploring tidal deformability

In this work we consider the vanishing complexity factor scenario [Phys Rev D 97: 044010, 2018] which has opened up a whole new way of generating solutions to the Einstein field equations for the spherically symmetric structure of celestial bodies. By using this very rare condition on the system of two metric potentials [Eur Phys J C 82:706, 2022], viz. gtt and grr, we make reduce it to a uni-metric potential system satisfying all physical conditions. Along with this, we further have considered that the spacetime is deformed by dark matter (DM) content in DM halos resulting into perturbations in the gtt and grr metric potentials. This DM deformation is mathematically done by the complete geometric decoupling (CGD) method where the decoupling parameter β decides the amount of DM content. In connection to the claimed post-merger object in the GW170817 event we have argued that if these compact stars were in galactic DM halos with the assumption that the radius remains the same, the compactness factor can grow within the range 1/3 to 4/9 and therefore can generate GW echoes. Additionally, we have presented effect of β on the generation of GW echoes in accordance with the observational constraints related to the compact stars GW190814, PSR J0740+6620, PSR J1614-2230, Cen X-3 and LMC X-4.
