    "abstract": "Immediately after they are born, neutron stars are characterized by an\nentropy per baryon of order unity and by the presence of trapped neutrinos. If\nthe only hadrons in the star are nucleons, these effects slightly reduce the\nmaximum mass relative to cold, catalyzed matter. However, if negatively charged\nparticles in the form of hyperons, a kaon condensate, or quarks are also\npresent, these effects result in an increase in the maximum mass of $\\sim\n0.2{\\rm M}_{\\odot}$ compared to that of a cold, neutrino-free star. This could\nlead to the delayed formation of a black hole; such a scenario is consistent\nwith our present knowledge of SN1987A.",
