TL;DR
This paper investigates the structure of protoneutron stars using finite-temperature Brueckner theory, focusing on how the low-density nuclear equation of state influences their maximum and minimum masses.
Contribution
It provides new insights into the sensitivity of protoneutron star mass limits to the low-density nuclear equation of state within the Brueckner framework.
Findings
Minimum mass slightly sensitive to low-density EOS
Maximum mass largely unaffected by low-density EOS
Highlights importance of EOS choice in neutron star modeling
Abstract
We study the structure of protoneutron stars within the finite-temperature Brueckner-Bethe-Goldstone theoretical approach, paying particular attention to how it is joined to a low-density nuclear equation of state (EOS). We find a slight sensitivity of the minimum value of the protoneutron star mass on the low-density equation of state, whereas the maximum mass is hardly affected.
