摘要：

A neutron star is formed by the evolution of a protoneutron star, so the study of the properties of protoneutron stars can help in understanding the structure and composition of neutron stars. The mass and radius of a cold neutron star calculated by the selected parameters are consistent with various existing astronomical observations. This set of parameters is then extrapolated to study the properties of a protoneutron star. This paper considers the isentropic protoneutron star matter with hyperons to study the temperature, composition, and os...
