2025-11-28 Stellar profiles and light curves of presupernova eruptions in low-mass core-collapse progenitors doi:10.57760/sciencedb.31295 en The data corresponds to a suite of simulations for the late-stage eruptions of low-mass core-collapse supernova progenitors with SNEC and STELLA. The progenitors are taken from Sukhbold et al. 2016 with initially solar metallicity and 9 to 10 solar masses. Energy is deposited suddenly at the base of the He layer and as a fraction of the combined binding energy of the He layer and H-rich envelope, defined as f_dep.The data contains 3 folders:snec_profiles: stellar profiles from SNEC non-radiative hydrodynamics simulations with 5 progenitors, with the zero-age main-sequence mass indicated by the name of the subfolders. In each subfolder, there are profiles with a 50-day cadence from full and H-only simulations for each f_dep, with filenames of the format 'profile_snec_full(H-only)_f_dep.dat'. The columns give radius, density, temperature, and velocity from left to right.stella_profiles: stellar profiles from STELLA radiative hydrodynamics simulations with only the 9.0 solar mass progenitor. There are profiles with a 10-day cadence for each f_dep, with filenames of the format 'profile_stella_f_dep.dat'. The columns give radius, density, temperature, and velocity from left to right.stella_lightcurves: associated precursor light curves from STELLA radiative hydrodynamics simulations with only the 9.0 solar mass progenitor. Each file with the name 'light_curve_f_dep.dat' contains time, luminosities, black-body temperature, and LSST multi-band photometry from left to right. The first row gives the names of the quantities for each column.
