Notes. The table columns correspond to the preSN mass, the ejecta mass, the ejecta kinetic energy (1 foe ≡1051 erg), the mean expansion rate , the cumulative yields of 4He, 12C, 14N, 16O, 24Mg, 28Si, 40Ca, and 56Ni prior to decay. The last two columns give the Lagrangian mass Msh adopted for the shell shuffling (see Sect. 2.3), as well as the ejecta velocity that bounds 99% of the total 56Ni mass in the corresponding model (this value corresponds roughly to the velocity at the Lagrangian mass Msh). All 56Ni masses used here were taken from the Kepler approximation to the P-HOTB neutrino simulation, and are between the best guess (56Ni+“Tr”) and generous upper bounds (3/4×(56Ni + “Tr”+ α)) defined by Ertl et al. (2020, see also Table A.2).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
