英文摘要 | GW170817 was really an event of the century that has opened the window to the frontier of multi-messenger astronomy and astrophysics. Gravitational waves from most likely the merging neutron stars were detected in LIGO-Virgo collaboration, GRB was observed in Fermi-GBM, and observed optical and near-infrared emissions in several Telescopes are consistent with those from radiative decays of r-process nuclei which are predicted theoretically in the nucleosynthesis calculation. Neutrinos were not detected unfortunately because of their too low flux from GW170817 that occurred at a distance 0.13 Gly away. We now await a nearby GW event (probably once per one-to-ten thousand years in our Milky Way) for spectroscopic observation of still unidentified r-process elements from neutron star mergers (NSMs). |
