compositions {stellaR}

Compostions of computed models

Description

The data sets gives the compositions of the computed models.

Usage

compositions

Format

A list containing 4 variables:

z

the initial metallicities of the models.

y

a data frame with the initial helium abundances of the models.

ml

the mixing-lengths of the models.

afe

the alpha-enhanchments of the models. It is coded 0 for [alpha/Fe] = 0.0 and 1 for [alpha/Fe] = 0.3.
