SVP Data and Codes

Download datasets and computational tools for radiative accelerations

Latest Release: January 2026

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.

Getting Started
