Download datasets and computational tools for radiative accelerations
These data (for C, N, O, Ne, Na, Mg, Al, Si, S, Ar, Ca, Sc, Fe and Ni) and codes have been released in 2026 (first release in 2020), and are discussed by Alecian & LeBlanc, 2020 (MNRAS), and Alecian, LeBlanc & Hui-Bon-Hoa, 2026 (A&A). The new version (January 2026) contains several improvements in the codes, and the SVP data have been extended to Sc and Ni.
Instructions to use the codes and data (content of the READme file).
Complete package including codes and data necessary for the implementation of the SVP method in stellar evolution programs. Also contains stellar models for testing.
Recommended: Update from the 2020 or 2024 versions to this new version (January 2026). Changes are detailed in the READme file.
