An advanced leakage scheme for neutrino treatment in astrophysical simulations
Albino Perego, Ruben Cabezón, Roger Käppeli
We present an Advanced Spectral Leakage (ASL) scheme to model neutrinos in the context of core-collapse supernovae and compact binary mergers. Based on previous gray leakage scheme…
Nucleosynthesis in the Ejecta of Neutron Star Mergers
Dirk Martin, Albino Perego, Almudena Arcones +2
Heavy elements like gold, platinum or uranium are produced in the r-process, which needs neutron-rich and explosive environments. Neutron star mergers are a promising candidate for…
Neutrino-driven winds in the aftermath of a neutron star merger: nucleosynthesis and electromagnetic transients
Dirk Martin, Albino Perego, Almudena Arcones +3
We present a comprehensive nucleosynthesis study of the neutrino-driven wind in the aftermath of a binary neutron star merger. Our focus is the initial remnant phase when a massive…
Pushing 1D CCSNe to explosions: model and SN 1987A
A. Perego, M. Hempel, C. Fröhlich +5
We report on a method, PUSH, for triggering core-collapse supernova explosions of massive stars in spherical symmetry. We explore basic explosion properties and calibrate PUSH such…
