Presupernova 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.

The Data

Presupernova zonal composition (mass fractions)
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.
