GW170817/SSS17a was an event of the century that opened a new window to multi-messenger astronomy and nuclear astrophysics. Optical and near-infrared emissions among many other observables suggest that their total energy release is consistent with radiative decays of r-process nuclei predicted theoretically although no specific r-process element was identified. Core-collapse supernovae (both...
End state of evolution of isolated and binary massive stars/black holes including various observational astrophysical properties of magnetized neutron stars and black holes are discussed. The energetics of rotating black holes and neutron stars is also analyzed. The possibilities of probing black holes nature through the study of their optical properties areexplored in detail.
Study the...
