Heavy Elements Nucleosynthesis On Accreting White Dwarfs: building seeds for the p-process
Umberto Battino, Marco Pignatari, Claudia Travaglio +5
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 ass…
Evaluation of the N(,p)O thermonuclear reaction rate and its impact on the isotopic composition of supernova grains
A. Meyer, N. de Séréville, A. M. Laird +12
It has been suggested that hydrogen ingestion into the helium shell of massive stars could lead to high C and N excesses when the shock of a core-collapse supernova p…
Origin of large meteoritic SiC stardust grains in metal-rich AGB stars
Maria Lugaro, Borbála Cseh, Blanka Világos +16
Stardust grains that originated in ancient stars and supernovae are recovered from meteorites and carry the detailed composition of their astronomical sites of origin. We present e…
129I and 247Cm in Meteorites Constrain the Last Astrophysical Source of Solar r-process Elements
Benoit Côté, Marius Eichler, Andrés Yagüe +12
The composition of the early Solar System can be inferred from meteorites. Many elements heavier than iron were formed by the rapid neutron-capture process (r process), but the ast…
