Postsupernova Composition

Below we provide preliminary data sets. Note that part of this data is not yet published in refereed journals and thus may be updated without notice.
We would appreciate if you contact us before using the data on this site for your publications.

Zonal Composition

Postsupernova zonal composition (mass fractions) of all ejecta 25000 seconds after core bounce.
Zone mass and mass coordinate (mass below) are given in grams.
"wind" includes all wind loss during the life of the star and its average composition. The mass below the wind is the total final mass of the star at core collapse.
"total" gives the sum of all ejecta including wind. Given are the remnant mass including fallback (column mass below), the total mass of ejecta (column zone mass) and the average mass fractions.

Some runs with varying explosion energy for a 15 solar mass star to study the r-process at the base of the helium shell.
WARNING: zones below #287 did not follow nucleosynthese entirely till core collapse!

Zonal Yields

Zonal yields 25000 seconds after core bounce.
The "yields" of each isotope also contain the contribution of all its radioactive progenitors, e.g., the value for ⁵⁶Co contains all of this isotope that is made directly during the explosion until the time of this snapshot plus all the ⁵⁶Ni; the value for ⁵⁶Fe contains all the ⁵⁶Fe that is made directly plus all the ⁵⁶Co made directly or indirectly, and so forth.
