摘要The influences of temperature on the constitutes, equations of state and masses of neutron star are studied in the frame work of the relativistic mean field theory for an interacting nucleons, hyperons, and mesons system. It is found that the appearing density of hyperons becomes smaller with temperature increasing. At higher hadron densities, the core of the neutron star is dominated by hyperons, in another words a neutron star transits into a hyperon star. The effects of temperature on the transition of a neutron star to a hyperon star are also investigated. The higher the temperature is, the smaller the transition density is. And it is also found that the equations of state for hadronic matter in the core region of a neutron star are approximately the same at different temperature. The calculated maximum masses of neutron stars are about 1.8M(circle dot), which are in consistence with the observation.
