We suggest the future detection of neutrinos from a Galactic core-collapse supernova can be used to infer the progenitor's inner mass density structure. We present the results from 20 axisymmetric core-collapse supernova simulations performed with progenitors spanning initial masses in the range 11--30Msun, and focus on their connections to the progenitor compactness. The compactness is a measure of the mass density profile of the progenitor core and recent investigations have suggested its… Expand

Measuring the distance and mass of galactic core-collapse supernovae using neutrinos
Neutrinos from a Galactic core-collapse supernova will be measured by neutrino detectors minutes to days before an optical signal reaches Earth. We present a novel calculation showing the ability ofExpand

Impact of binary interactions on the diffuse supernova neutrino background
Binary interactions, especially mass transfer and mergers, can strongly influence the evolution of massive stars and change their final properties and the occurrence of supernovae. Here, weExpand

Equation of State and Progenitor Dependence of Stellar-mass Black Hole Formation
The core collapse of a massive star results in the formation of a proto-neutron star (PNS). If enough material is accreted onto a PNS it will become gravitationally unstable and further collapse intoExpand
Robust measurement of supernova ν e spectra with future neutrino detectors
Measuring precise all-flavor neutrino information from a supernova is crucial for understanding the core-collapse process as well as neutrino properties. We apply a chi-squared analysis for differentExpand
Long-term Simulations of Multi-Dimensional Core-collapse Supernovae: Implications for Neutron Star Kicks
Core-collapse supernovae (CCSNe) are the final stage of massive stars, marking the birth of neutron stars (NSs). The aspherical mass ejection drives a natal kick of the forming NS. In this work weExpand
Fast Flavor Depolarization of Supernova Neutrinos.
A theory of fast flavor depolarization is presented, explaining how neutrino flavor differences become smaller, i.e., depolarize, due to diffusion to smaller angular scales, and it is shown that transverse relaxation determines the epoch of this irreversibledepolarization. Expand
