Abstract
From the relativistic mean field model and the theory of weak interactions, the effects of ∑ hyperons on neutron stars are studied. Results show that ∑ hyperons have effects on the three meson fields.They change the particle distribution and mass-radius relation of neutron stars. The effects of ∑ on the cooling of neutron stars are obviouly. The density ranges where direct lerca processes of both electorns and muons are allowed can be changed. On the other hand, ∑ hyperons lower the neutrino emissivity obviously, so it maybe not suitable for the fast cooling of neutron stars.关键词
