Welcome to Trac for XNET

Welcome to the XNet home page. XNet is a thermonuclear reaction network for astrophysical applications, using the fully Implicit Backward Euler scheme. It is written in portable FORTRAN 90 and makes use of a variety of matrix solving packages to obtain excellent speed (as much as 50% of peak) on as many platforms as possible.

If you want to learn the basics of how thermonuclear reaction networks function, we recommend the following sources.

"Thermonuclear Reaction Networks for Astrophysics" by Raph Hix, http://astro.phys.utk.edu/_media/gallery:networks.pdf

Tools and Toys for Nuclear Astrophysics: Nuclear Reaction Network Techniques by Frank Timmes, http://cococubed.asu.edu/talk_pages/jina.shtml

Thermonuclear Kinetics in Astrophysics by Raph Hix and Brad Meyer http://dx.doi.org/10.1016/j.nuclphysa.2004.10.009

Supernovae and Nucleosynthesis: An Investigation of the History of Matter, from the Big Bang to the Present by Dave Arnett http://press.princeton.edu/titles/5859.html

Someday, we'll make a list of publications using XNet, but that will wait...

If you're interested in using XNet for science, we now have a public version available to download https://wikihost.nscl.msu.edu/talent/doku.php?id=rxnnetcode. This FORTRAN program allows post-processing nucleosynthesis calculations following pre-calculated thermodynamic histories for arbitrary nuclear reaction networks, using data in the REACLIB format https://groups.nscl.msu.edu/jina/reaclib/db/.
