Temperature dependence of proton localization for Skyrme nuclear interactions

Włodzimierz Wójcik


In this paper, our earlier approach to proton localization in neutron star matter to finite temperatures is extended. The Skyrme forces were chosen to describe interactions in nuclear matter. The dependence of threshold density on temperatures for proton localization was obtained and these results were compared with those calculated earlier for the Friedman-Pandharipande-Ravenhall potential.
