ratelib

A simple interface to handle REACLIB format databases of astrophysical reaction rates.

Standard REACLIB database can be downloaded from here: https://reaclib.jinaweb.org

Requirements

• Python 3.5+
• numpy
• scipy

Installation

Package ratelib can be installed via pip:

  pip install ratelib

You can also install the most recent version from the git repository with following commands:

  git clone https://github.com/kompoth/ratelib
  cd ratelib
  python -m build
  pip install dist/*.whl

Usage

A simple script example.py is located in the root of the git repository. It loads a version of REACLIB, provided as the first argument, and draws a nuclei chart of weak decay rates at the temperature of 1 GK.

This script requires matplotlib>=3.4.

Classes

• Library: Collection of reaction rates, database itself
• Rate: Reaction rate class with properties from REACLIB format
• RateFilter: Class for filtering rates in Library
• Nucleus: Basic class to unify different nucleus denotions
