Abstract

The effect of interaction between hyperons on the moment of inertia of proto neutron star (PNS) PSR J0740+6620 is examined with relativistic mean field theory considering the octet of baryons. The nucleon coupling constant GM1 is used and the temperature of the PNS is chosen as \(T=20\) MeV. Under the constraint of the mass \(M=2.08 M_{\odot }\), considering the interaction between hyperons, the radius of the PNS PSR J0740+6620 is reduced by 0.08% from \(R=14.518\) km to \(R=14.507\) km and the moment of inertia of the PNS PSR J0740+6620 is reduced by about 0.49% from \(I=2.460 \times 10^{45}\) g  cm\(^{2}\) to \(I=2.448 \times 10^{45}\) g cm\(^{2}\), respectively. The moment of inertia of the PNS has a peak with the change of central energy density \(\varepsilon _{c}\), mass M or radius R. Considering the interaction between hyperons, the value of the moment of inertia I of the PNS corresponding to this peak will decrease.
