Scientific paper

The authors have improved the Wallace and Woosley estimates of the 19Ne(p,γ)20Na and 15O(α,γ)19Ne reaction rates at stellar energies by using the most recent experimental and theoretical data and a firmer theoretical background. They find a considerable increase in the 19Ne(p,γ)20Na reaction rate at temperatures T9 ≤ 0.3, which may lead to a greater production of intermediate mass elements in the rp-process in stellar evolution.
