| + | **Input Parameters** | ||
| + | |||
| + | Extracted input parameters from T. Fischer et al. using GSYS 2.4 (a program to extract data points from graphs) http://www.jcprg.org/gsys | ||

| + | **Simulations** | ||
| + | |||
| + | Ran simulations using xnet for different $Y_e$ values and different progenitor masses. We tried to see the effect of the presence of neutrinos and anti-neutrinos in the r-process abundance patern. | ||
