Nuclear Reactions in the Stars and in the Laboratory

The paper discusses the reaction rates at low energies, needed for the description of nucleosynthesis processes. In contrast to the stellar environment, the laboratory measurements are complicated by the coulomb potential screening caused by bound electrons. The consequences of recent 7Be+p reaction measurements on solar modelling are presented. The new high-energy laser facilities will open new possibilities for measurements of stellar reaction rates.
