The p-process of stellar nucleosynthesis: astrophysics and nuclear physics status

The p-process of stellar nucleosynthesis is aimed at explaining the production of the stable neutron-deficient nuclides heavier than iron that are observed up to now in the solar system exclusively. Various scenarios have been proposed to account for the bulk p-nuclide content of the solar system, as well as for deviations ('anomalies') with respect to the bulk p-isotope composition of some elements discovered in primitive meteorites. The astrophysics of these models is reviewed, and the involved nuclear physics is discussed, including a brief account of recent experimental efforts. Already published results are complemented with new ones. A specific attention is paid to the very rare odd-odd nuclides 138La and 180Tam, as well as to the puzzling case of the light Mo and Ru isotopes. Astrophysics and nuclear physics prospects of improvements in the p-process modeling are presented
