Abstract：
A chiral hadronic model is extended to investigate the influences of trapped neutrinos on the equation of state of dense matter and structure of protoneutron stars. Our results show that trapped neutrinos lead to the increase of proton fraction and make the equation of state of dense matter soft. Furthermore, maximum masses and radii of protoneutron stars decrease when neutrinos are trapped.
