N1 - We are grateful to Evan O’Connor and Christian Ott for making their numerical simulation code GR1D publicly available, and to Evan O’Connor for help in technical issues related to running the code. We thank Avital Dery, Yossi Nir, and Eli Waxman for useful discussions, John Beacom for comments on the manuscript, and Doron Kushnir for many insightful discussions and for providing MESA profiles and CITE numerical simulation data. The work of N. B. and K. B. was supported by Grant No. 1937/12 from the I-CORE program of the Planning and Budgeting Committee and the Israel Science Foundation and by Grant No. 1507/16 from the Israel Science Foundation. K. B. is incumbent of the Dewey David Stone and Harry Levine career development chair. G. D. A. is supported by the Simons Foundation Origins of the Universe program (Modern Inflationary Cosmology collaboration).

N2 - We study the ratio of neutrino-proton elastic scattering to inverse beta decay event counts, measurable in a scintillation detector like JUNO, as a key observable for identifying the explosion mechanism of a galactic core-collapse supernova. If the supernova is not powered by the core but rather, e.g., by collapse-induced thermonuclear explosion, then a prolonged period of accretion-dominated neutrino luminosity is predicted. Using 1D numerical simulations, we show that the distinct resulting flavor composition of the neutrino burst can be tested in JUNO with high significance, overcoming theoretical uncertainties in the progenitor star profile and equation of state.
