Heavy elements nucleosynthesis on accreting white dwarfs : Building seeds for the p-process
Battino, U.; Pignatari, M.; Travaglio, C.; Lederer-Woods, C.; Denissenkov, P.; Herwig, F.; Thielemann, F.; Rauscher, T. (2020-10-01)The origin of the proton-rich trans-iron isotopes in the Solar system is still uncertain. Single-degenerate thermonuclear supernovae (SNIa) with n-capture nucleosynthesis seeds assembled in the external layers of the ... -
Radiogenic p-isotopes from type Ia supernova, nuclear physics uncertainties, and galactic chemical evolution compared with values in primitive meteorites
Travaglio, C.; Gallino, R.; Rauscher, T.; Dauphas, N.; Röpke, F. K.; Hillebrandt, W. (2014-11-10)The nucleosynthesis of proton-rich isotopes is calculated for multi-dimensional Chandrasekhar-mass models of Type Ia supernovae (SNe Ia) with different metallicities. The predicted abundances of the short-lived radioactive ... -
Role of Core-collapse Supernovae in Explaining Solar System Abundances of p Nuclides
Travaglio, C.; Rauscher, T.; Heger, A.; Pignatari, Marco; West, C. (2018-02-07)The production of the heavy stable proton-rich isotopes between 74Se and 196Hg - the p nuclides - is due to the contribution from different nucleosynthesis processes, activated in different types of stars. Whereas these ... -
Uncertainties in the production of p nuclides in thermonuclear supernovae determined by Monte Carlo variations
Nishimura, N.; Rauscher, T.; Hirschi, R.; Murphy, A. St J.; Cescutti, G.; Travaglio, C. (2018-03-01)Thermonuclear supernovae originating from the explosion of a white dwarf accreting mass from a companion star have been suggested as a site for the production of p nuclides. Such nuclei are produced during the explosion, ...
