Nuclear astrophysics using radioactive nuclear beams is one of the major research topics in Louvain-la-Neuve. Recently, experiment aiming at the measurement of (α,γ), and (α,p) reactions have been performed. The 15O(α,γ)19Ne reaction was studied using an indirect method based on the study of the 18Ne(d,p)19Ne∗. Preliminary results of a new analysis of this experiment are presented here.The new mass recoil separator ARES, coupled to the new cyclotron CYCLONE-44, is now operational. The ARES project status and results of performance tests are reported here.
