| Abstract: |
This study investigates the mass-radius evolution and stability of the slowly rotating anisotropic pulsar J 0 3 4 8 + 0 4 3 2 within the Krori–Barua spacetime in f (R , T) gravity. Rotational effects on stellar structure are examined using a modified Chaplygin gas equation of state with the linear form f (R , T) = R + 2 ξ T. The model supports the existence of supermassive neutron stars in the lower mass gap, consistent with NICER and gravitational-wave constraints and highlights the critical role of positive pressure anisotropy. Comparison with general relativity confirms physical consistency, stability and astrophysical viability. [ABSTRACT FROM AUTHOR] |
