 +**Accomplishments:​**
 +
 +We found a set of astrophysical conditions for the s-process in AGB stars, a temperature of 0.28GK and baryon density of 2.6e+3 g/cm^3.
 +
 +We incorporated those conditions into xnet reaction network with an initial abundance of <​sup>​4</​sup>​He and <​sup>​13</​sup>​C in order to produce neutrons and a 1% abundance of <​sup>​56</​sup>​Fe.
 +
 +We also developed a python script to extract the abundances at a time step from the xnet binary files.
 +
 +We then generated final abundances for iron concentrations of .1%, 1%, and 10%.
