Core-collapse Supernovae: From Neutrino-driven 1D Explosions to Light Curves and Spectra

We present bolometric and broadband light curves and spectra for a suite of core-collapse supernova models exploded self-consistently in spherical symmetry within the PUSH framework. We analyze broad trends in these light curves and categorize them based on morphology. We find that these morphological categories relate simply to the progenitor radius and mass of the hydrogen envelope. We present a proof-of-concept sensitive-variable analysis, indicating that an important determining factor in the properties of a light curve within a given category is Ni-56 mass. We follow spectra from the photospheric to the nebular phase. These spectra show characteristic iron-line blanketing at short wavelengths and Doppler-shifted Fe ii and Ti ii absorption lines. To enable this analysis, we develop a first-of-its-kind pipeline from a massive progenitor model, through a self-consistent explosion in spherical symmetry, to electromagnetic counterparts. This opens the door to more detailed analyses of the collective properties of these observables. We provide a machine-readable database of our light curves and spectra online at go.ncsu.edu/astrodata.

Automated summary

This study presents bolometric and broadband light curves and spectra for core-collapse supernova models, categorizing them based on progenitor radius and hydrogen envelope mass. The research also highlights the importance of Ni-56 mass in determining the properties of light curves within specific categories. The development of a unique pipeline from progenitor modeling to electromagnetic counterparts allows for more detailed analyses of these observable properties.
