Comparison of Electron Capture Rates in the N = 50 Region using 1D Simulations of Core-collapse Supernovae

Recent studies have highlighted the sensitivity of core-collapse supernovae (CCSNe) models to electron-capture (EC) rates on neutron-rich nuclei near N=50 closed-shell region. In this work, we perform a large suite one-dimensional CCSN simulations for 200 stellar progenitors using recently updated EC in For comparison, repeat two previous implementations rates: microphysical library with parameterized (LMP), and an older independent-particle approximation (IPA). We follow through shock revival up several seconds post-bounce, show that produce consistent imprint properties, often surpassing role progenitor itself. Notable impacts include timescale core collapse, electron fraction mass inner at bounce, accretion rate shock, success or failure revival, properties central compact remnant. also compare observable neutrino signal neutronization burst DUNE-like detector, find counts mean energies. Overall, result are intermediate between LMP IPA, yet slightly more favorable explosion than both.
