A look inside the sun's fire: New measurements point at slower burn-in phase of hydrogen burning

Nuclear astrophysics studies the evolution of the elements in the universe since its creation. The astrophysical models rely on parameters that scientists deduce from laboratory measurements. Nuclear reactions play a crucial role inside stars. A team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), together with researchers from Italy, Hungary and Scotland, has now reinvestigated one of the central reactions at the Dresden Felsenkeller accelerator with a surprising result, as reported in the journal Physical Review C.
