Contribution
It provides analytical parametrizations of hypernuclear matter results and investigates the effects of finite temperature and trapping on hyperonic stars.
Findings
Finite temperature significantly affects hyperonic star structure.
Trapping influences the properties of hyperonic matter.
Analytical parametrizations facilitate future studies.
Abstract
We perform Brueckner-Hartree-Fock calculations of hypernuclear matter at finite temperature and provide convenient analytical parametrizations of the results. We study then the properties of (proto)neutron stars containing hyperons. We find important effects of trapping and finite temperature on the structure of hyperonic stars.
