摘要
GRB 990123 may have produced 4 x 10(54) ergs in gamma rays unless, as seems to be the case, it was significantly beamed. Even with beaming, it may be beyond the limiting binding energy available for neutron star mergers in the Schwarzschild metric. Neutron stars of similar to 10 M. are permitted in the Yilmaz metric. A merger of two neutron stars of about 10 M. could release approximately 3 x 10(55) ergs. The spectral state switches of the galactic black hole candidates may be the signatures of the magnetic fields of such massive neutron stars.
