Exotic nucleosynthesis processes are responsible for the production of elements heavier than iron and for the luminosity profiles of the so-called X-ray bursts. Nuclear structure inputs into the rp-process, which powers X-ray bursts, have been shown to be very sensitive to not only the decay and electron capture rates of nuclei involved, but also to some of the finer structure of these nuclei. Experimental and theoretical inputs of the rp-process are explored, and sensitivities to nuclear structure are presented. In addition, an overview of experiments to constrain the r-process will be presented.
