With DD-MEI, GL85, GL97, and GM1, baryon octets appear in the PNS PSR J0737-3039A. With NL2, only the baryons n, p, Λ, \begin{document}$\Sigma^{0}$\end{document}, \begin{document}$\Sigma^{-}$\end{document}, \begin{document}$\Xi^{0}$\end{document}, and \begin{document}$\Xi^{-}$\end{document} are present. Corresponding to the same baryon density, the relative densities of the same baryon in the PNS PSR J0737-3039A calculated using different nucleon coupling constants differ greatly. The central relative baryon densities of the PNS PSR J0737-3039A calculated using different nucleon coupling constants also differ greatly."> Properties of proto neutron star PSR J0737-3039A -
