A precise understanding of nuclear reactions involved in hydrogen burning is a fundamental requirement for solar and stellar modeling. In the last decade, since the INT workshop Solar Fusion cross sections II took place, the need for accurate stellar and solar models has increased significantly. On the one hand, large-scale astronomical surveys have become the common place for studies of Galactic stellar populations, galactic archaeology, and characterization of exoplanet host stars, among other fields. Moreover, the coming of age of asteroseismology, first with Kepler, now with TESS, and in the mid-term future with PLATO, allows us to study the interior of other stars in a way that had previously only been possible for the Sun.
