+**Initial Goals:**
+Determine theoretical astrophysical conditions for AGB stars during the s-process.
+Create reaction network for both <sup>56</sup>Fe and solar abundance seeds.
+Create toolkit to read binary file into format appropriate for abundance graphing.
+Modify xnet code to allow the definition of a time-dependent neutron flux.
+**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%.
