Influence of Yano-Schrodinger gravity on stellar structures

Abstract

This study delves into the dynamics of stellar objects within the framework of Yano-Schrödinger gravity. We adopt the Krori-Barua metric potentials, $\nu \left(r\right)=B{r}^2+C\text{and}\lambda \left(r\right)=A{r}^2,$ where $A,B$, and $C$ are constants, to characterize the internal structure of these stars. By imposing boundary conditions with the Schwarzschild solution as the external geometry, we explore the stellar profiles using Yano-Schrödinger gravity for a spherically symmetric framework. Our analysis provides a detailed graphical depiction of energy density, radial and tangential pressures, anisotropy, and adiabatic index. Moreover, we evaluate the equilibrium state through the modified Tolman–Oppenheimer–Volkoff equation. We further investigate key attributes of compact stars, such as the mass–radius relationship, compactness factor, and redshift function. The results demonstrate that all aspects are fulfilled, affirming the stability and physical viability of the considered stellar models.
