Buchdahl quark stars within f(Q) theory

In the present paper, authors study strange stars with MIT Bag EoS admitting Buchdahl symmetry (non-singular and physically viable metric potential) in both linear $$f(Q)=aQ+b$$ nonlinear $$f(Q)=Q+aQ^b$$ forms of modified symmetric teleparallel gravitation. order to obtain correct form coefficients, they matched interior star space-time exterior Schwarzschild vacuum space-time. As a candidate, PSRJ1416-2230 has been used mass $$M=1.69M_\odot$$ radius $$R=9.69R_\odot$$ . For either f(Q) gravities, probed Null, Dominant Strong Energy Conditions as well radial, tangential Equation State (EoS), gradients perfect fluid energy-momentum tensor elements, Tolman–Oppenheimer–Volkoff equilibrium condition, relativistic adiabatic index causality conditions, surface redshift. It was found that gravity show behavior, respect energy bounds $$0\le \omega \le 1$$ redshift does not exceed 2, expected.
