From the s-Process to the i-Process: A New Perspective on the Chemical Enrichment of Extrinsic Stars
GalaxiesSeparating stars enriched in the s- and r-processes of nucleosynthesis is usually achieved by analyzing the element ratios of s-process elements (like Ba or La) to r-process elements (like Eu).

The heavy-element abundances of AGB stars and the angular momentum conservation model of wind accretion for barium stars [PDF]
, 2000 Adpoting new s-process nucleosynthesis scenario and branch s-process path, we calculate the heavy-element abundances and C/O ratio of solar metallicity 3M_sun TP-AGB stars.

, 2022 Cosmic nucleosynthesis had been one of INTEGRAL’s major science targets. The SPI spectrometer delivered important measurements, both from targets of opportunity in the form of stellar explosions and their shortlived radionuclides, and from cumulative emission of long-lived radioactive isotopes. We review the lessons learned on explosive nucleosynthesis

Recent Advances in Understanding R-Process Nucleosynthesis in Metal-Poor Stars and Stellar Systems
UniverseThe rapid neutron-capture process (r-process) is responsible for the creation of roughly half of the elements heavier than iron, including precious metals like silver, gold, and platinum, as well as radioactive elements such as thorium and uranium ...
