ABSTRACT.  We investigate for the first time the newly born neutron star (NS) containing both hyperons and kaons as strange hadrons within the relativistic mean-field theory. It is found that the maximum baryonic mass of the newly born NS is lower than that of the cold deleptonized NS. Against the suggestion by Brown and Bethe, there is no possibility of the delayed collapse of NS to low-mass black hole.
