Contents: The focus this project is to study the impact of radiation heating on the hydrodynamics and nucleo-synthesis during the neutrino driven wind phase of Type II supernova core-collapse. In essence, we are trying to see if thr r-process becomes feasible by increasing the the entropy in the wind. For this purpose, we are going to add radiation heating code (with central luminosity varying 10^51-10^53 erg/s) to the hydrodynamic simulations internal energy. Once the simulation is complete, we will use the reaction network code for each cell in our simulation by using the temperature and density input from hydro across multiple time slices.

The input we use is taken from “THE PHYSICS OF PROTONEUTRON STAR WINDS: IMPLICATIONS FOR R-PROCESS NUCLEOSYNTHESIS” from A.Thompson etal. The wind simulation in the paper is spherically symmetric and the input we use is taken after a couple of seconds after core collapse. We will focus in temperature and density range of the star that is appropriate for nuclear reactions to happen (not NSE).
