Non-LTE models for He and Sr in kilonova ejecta show that ~1% He or 1-10% Sr can reproduce the 1μm absorption feature in AT2017gfo, implying low-Ye, low-entropy r-process conditions.
Hadronic pp collisions dominate pair loading via pion cascades in magnetar-like outflows from neutron star mergers, channeling magnetic energy into e± and seeding neutrinos up to ~300 MeV.
A Kokkos-based C++ port of the SACRA numerical relativity code achieves ~10x speedup on GPU/APU over the Fortran CPU version while preserving waveform accuracy, pi-symmetry, and second-order convergence.
