Old Data, New Forensics: The First Second of SN 1987A Neutrino Emission
Shirley Weishi Li, John F. Beacom, Luke F. Roberts +1
The next Milky Way supernova will be an epochal event in multi-messenger astronomy, critical to tests of supernovae, neutrinos, and new physics. Realizing this potential depends on…
Proto-Neutron Star Convection and the Neutrino-Driven Wind: Implications for the r-Process
Brian Nevins, Luke F. Roberts
The neutrino-driven wind from proto-neutron stars is a proposed site for r-process nucleosynthesis, although most previous work has found that a wind heated only by neutrinos canno…
Angular Momentum Transport in Proto-Neutron Stars and the Fate of Neutron Star Merger Remnants
Ben Margalit, Adam S. Jermyn, Brian D. Metzger +2
Both the core collapse of rotating massive stars, and the coalescence of neutron star (NS) binaries, result in the formation of a hot, differentially rotating NS remnant. The times…
-process Nucleosynthesis and Kilonovae from Hypermassive Neutron Star Remnants
Sanjana Curtis, Philipp Mösta, Zhenyu Wu +4
We investigate -process nucleosynthesis and kilonova emission resulting from binary neutron star (BNS) mergers based on a three-dimensional (3D) general-relativistic magnetohydr…
HARM3D+NUC: A new method for simulating the post-merger phase of binary neutron star mergers with GRMHD, tabulated EOS and neutrino leakage
Ariadna Murguia-Berthier, Scott C. Noble, Luke F. Roberts +25
The first binary neutron star merger has already been detected in gravitational waves. The signal was accompanied by an electromagnetic counterpart including a kilonova component p…
Exciting Prospects for Detecting Late-Time Neutrinos from Core-Collapse Supernovae
Shirley Weishi Li, Luke F. Roberts, John F. Beacom
The importance of detecting neutrinos from a Milky Way core-collapse supernova is well known. An under-studied phase is proto-neutron star cooling. For SN 1987A, this seemingly beg…
