Weak rate library
A new open source weak interaction rate library with the aim of standardizing the incorporation of weak rates in astrophysical simulations is now available. This library brings together all major weak interaction rate tables and is easily expanded to incorporate new tables of arbitrary grid resolution and ranges of density and temperature. Its first implementation was in the sensitivity study of core-collapse supernovae to nuclear electron capture (reference [1] below). For that work, this library was implemented into the neutrino-interaction library NuLib, by Evan O'Connor.
UPDATE: Version 1.2 of the weak interaction rates library is now available. It includes two new sets of rate tables and a more sophisticated rate approximation method, all referenced below. Also included with this version is a single recommended rate table, which incorporates rates from all available tables based on their priority within the weak rate library. The following figure provides an overview of the sets used in the creation of the library. Please refer to refs [1] and [10] if you use to version 1.2 of the rate table, as well as to the individual rate sets (see references below).
