We present r-Java 2.0, an r-process nucleosynthesis code equipped with a simple-to-use graphical user interface (GUI) that solves a full reaction network of over 8000 nuclei. Built to be an instrument for the nuclear physics and astrophysics community, r-Java 2.0 allows users to test the effects of varying nuclear reaction rates as well as study the r-process in a host of different astrophysical environments. On top of solving an r-process reaction network over a large range of input parameters r-Java 2.0 computes; nuclear statistical equilibrium (NSE) distributions, fission mass fragmentation and allows for the investigation of individual nuclear reactions.
r-Java is no longer unavailable for the general public to use. It has been supersede by SiRop.
If you have found r-Java useful in your own research, please reference Paper I and II from the links below.
This tutorial provides a general overview of r-Java including how to get started
This tutorial shows you how to set up different graphs
This tutorial shows you how to setup initial mass fractions
This video shows a simulation with periodic table and chart of nuclides output
We have tried to make r-Java as user friendly as possible, but if you need help running the code, have questions about how it works or would like to see features added please contact us!
