Complexity-free Vaidya-Tikekar model describing self-bound compact objects by gravitational decoupling

Abstract

Abstract In this article, using gravitational decoupling under vanishing complexity condition, an anisotropic solution to spherically symmetric compact stars has been investigated. After obtaining the solution, a detailed physical analysis including thermodynamic parameters, mass-radius ratio, and stability analysis of the model corresponding to the secondary component of the GW190814 event has been done. To test the effect of gravitational decoupling on the mass-radius ratio, we fixed the mass of the secondary component of the GW190814 event corresponding to the pure general relativity scenario. Alongside this, we also predicted the radii and mass-radius ratio of 11 different compact stars using observational data of their masses for different values of β. Furthermore, the hydrostatic balance has been analyzed using the modified Tolman-Oppenheimer-Volkoff (TOV) equation. The physical analysis shows that our results are in good agreement as far as observational data is concerned.
