Network calculations


libnucnet is a collection of libraries developed at Clemson University by Brad Meyer and his collaborators for network calculation application. It is available under the GNU General Public License. Information about the code can be found here: https://sourceforge.net/projects/libnucnet.

NucNet-Tools is a set of codes based on libnucnet for post-processing network calculations. It provides tools useful for preparing the input data, running the calculations as well as analyzing the data and plotting the results. I use this code, combined with additional programs that are specific to my calculations, to investigate production of p-nuclei and sensitivity of the p-nuclei abundances to the nuclear reaction rates and stellar environment conditions.

How to install the code

First be sure to install the Boost C++ libraries appropriate for your operating system, as described in http://sourceforge.net/u/mbradle/wiki/tutorials/. Check out the NucNet Tools with a command: svn checkout svn://svn.code.sf.net/p/nucnet-tools/code/trunk nucnet-tools-code This will create a folder nucnet-tools-code and download from the svn source all available files. Next, change into the nucnet-toolscode/examples/network directory and make the single …

Getting started

Update reaction and nuclide data Recent version of REACLIB can be downloaded from https://groups.nscl.msu.edu/jina/reaclib/db /library.php already in XML format. However the nuclide and reaction data are provided in two separate files that have to be merged into one file. This can be done by running: ./merge_net nuclide_data.xml reaction_data.xml output.xml in nucnet-tools/vendor/libnucnet/0.15/examples directory. Preparing input file …

Sample result for p-process calculations

This is a sample video showing evolution of the p-process during a shock wave propagation through an oxygen-neon burning layer of a 25 solar mass type II Supernova. At the beginning the s-process nuclei exist in the environment. The inset shows the temperature in GK and the red dot indicate the current temperature value. As …
