Introduction

A variety of joint research activities (JRAs) in ChETEC-INFRA will compile information and data for researchers in their respective fields.

This includes databases of:

  • surface abundance corrections for effects of stellar evolution (WP5)
  • 3D NLTE abundance corrections for a number of key s-process chemical elements (WP5)
  • AGB/binary stars (WP6)
  • stable isotope anomalies in bulk meteoritic materials (WP9)

Other goals in ChETEC-INFRA revolve around software tools for nuclear astrophysics calculations, and how to make these tools more easily accessible to the community.

The projects pursued so far are listed below:

Databases

Barium Star Repository

A database of Barium stars has been created and filled with first data. The data collection is openly available as a GitHub repository and will be reviewed / expanded on a regular basis.

Nuclear Reaction Rates – ChANUREPS

ChANUREPS Logo

ChANUREPS is a platform where the nuclear-astrophysics community is providing new nuclear reaction rates, and other users can find them easily open source with a simple format. These rates could be used for many research tasks, such as nucleosynthesis calculations, comparison when new rates are becoming available and much more.

Stellar Trajectories – ORChESTRA

ORChESTRA (Online Repository of ChETEC Stellar TRAjectories) is developed and maintained as a free open-source platform under ChETEC-INFRA. The aim of ORChESTRA is to publish regularly a fully documented library of certified trajectories, covering a wide range of stellar conditions for nuclear astrophysics simulations. Trajectories with initial conditions, origin and relevant information will be fully available.

Trajectory data in ORChESTRA is available on Zenodo.

Courses and Tutorials

Galactic Chemical Evolution Modelling

A video course on GCE Modelling with NuPyCEE and JINAPyCEE that guides through the initial setup, and their application in two lab projects.

The course can be found on this page.

Stellar Nucleosynthesis Tools for HPC Clusters

Series of video tutorials providing online training courses for stellar evolution and nucleosynthesis tools on the ChETEC-INFRA Viper HPC facility (tutorials also useful for other HPC systems and servers/desktops/laptops).

The first video of the series is available on the ChETEC-INFRA YouTube Channel.

Multidisciplinary Guide to Astronuclear Science Cases

This deliverable to WP6 will build on the work of JRA1, JRA2 and JRA3 to provide the ChETEC-INFRA community with textbook examples of cross-collaboration between astronomers, astrophysicists, nuclear physicists and cosmochemists. A first version of this guide is available here, and will be expanded in the future.


Tools

Translation of Stellar Yield Predictions for Comparison with the Laboratory Analysis of Meteorites

A git repository with a Jupyter notebook providing the tools to translate predictions from stellar yield calculations into the units and representation obtained from laboratory analysis of meteorites.

The repository is available on GitHub.
