It provides the first detailed 1D calculations of neutrino opacities and cooling processes specific to proto-strange stars, highlighting their unique evolution.
Findings
Longer deleptonization timescales than proto-neutron stars
Distinct features in the neutrino emission signals
Insights into the cooling behavior of strange stars
Abstract
We perform 1D calculations of neutrino opacities inside a young "strange star" assumed to be the result of the conversion process of a normal neutron object. We evaluate the deleptonization and cooling timescales, which happen to be longer than the proto-NS analogues, and preliminary address the features of the emerging neutrino signal.
