We studied recent observation data of pulsar masses and radii of PSR J0740+6620, PSR J0348+0432, and PSR J1614–2230 from different measurements, based on the extended version of σ-ω model. Throughout our analysis, we assumed that these pulsars are maximal-mass compact stars, thus we applied the core approximation. Based on the linear relation between the microscopic and macroscopic parameters of compact stars evaluated by our model, we estimated the average Landau mass mL = 752.46- 42.5+ 49.1 MeV and compressibility K = 261.7- 28.0+ 57.2 MeV.
