Effect of nuclear structure on Type Ia supernova nucleosynthesis [PDF]
, 2000 The relationship among nuclear structure, the weak processes in nuclei, and astrophysics becomes quite apparent in supernova explosion and nucleosynthesis studies.

Big-Bang Nucleosynthesis [PDF]
, 2014 A critical review is given of the current status of cosmological nucleosynthesis. In the framework of the Standard Model with 3 types of relativistic neutrinos, the baryon-to-photon ratio, $\eta$, corresponding to the inferred primordial abundances of ...

PUSHing Core-collapse Supernovae to Explosions in Spherical Symmetry. III. Nucleosynthesis Yields [PDF]
Astrophysical Journal, 2018 In a previously presented proof-of-principle study, we established a parameterized spherically symmetric explosion method (PUSH) that can reproduce many features of core-collapse supernovae (CCSNe) for a wide range of pre-explosion models.

Geostandards and Geoanalytical Research, Volume 48, Issue 4, Page 863-885, December 2024.Key Points A method is described to obtain high precision Sn isotope ratios using the double spike technique in geological reference materials containing 0.03 to 7 μg g−1 of Sn. δ122/118Sn values are reported for sixteen geological RMs. Improved precision was achieved compared with previous studies by using low concentration Sn analyte.

β-delayed Fission in r-process Nucleosynthesis [PDF]
Astrophysical Journal, 2018 We present β-delayed neutron emission and β-delayed fission (βdf) calculations for heavy, neutron-rich nuclei using the coupled Quasi-Particle Random Phase Approximation plus Hauser-Feshbach (QRPA+HF) approach.

Geostandards and Geoanalytical Research, Volume 48, Issue 4, Page 795-805, December 2024.Key Points Isotopic reference materials are rarely cross‐examined. An optimised regression model and MC‐ICP‐MS offer a cost‐effective way to assess the reliability of values assigned to multi‐isotope reference materials. A significant lack of consistency has been observed in the long‐standing isotopic reference materials for nickel and zinc. Calibrated

Nucleosynthesis in Thermonuclear Supernovae [PDF]
, 2017 The explosion energy of thermonuclear (Type Ia) supernovae is derived from the difference in nuclear binding energy liberated in the explosive fusion of light 'fuel' nuclei, predominantly carbon and oxygen, into more tightly bound nuclear 'ash' dominated by iron and silicon group elements.
