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. We find a slight sensitivity of the minimum value of the protoneutron star mass to the low-density equation of state, whereas the maximum mass is hardly affected.
Key words: dense matter / equation of state / stars: interiors / stars: neutron
