Structure effects of 20N in elemental abundance estimations during explosive nucleosynthesis [PDF]
EPJ Web of ConferencesMost nuclei far from the valley of stability, and typically near the drip lines, exhibit exotic features that have challenged our current understanding of nuclear structure.

Mass‐Loss, Composition and Observational Signatures of Stellar Winds From X‐Ray Bursts
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT X‐Ray bursts (XRBs) are powerful thermonuclear events on the surface of accreting neutron stars (NSs), which can synthesize intermediate‐mass elements. Although the high surface gravity prevents an explosive ejection, a small fraction of the envelope may be ejected by radiation‐driven winds.

Nucleosynthesis and Nucleo-Cosmochronology
, 2004 I discuss a few selected topics on nucleosynthesis and nucleo-cosmochronology in faint, if not totally illusory, hopes of helping to gain a clear perspective of the future astronuclear physics.

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.

Coulomb screening in linear coasting nucleosynthesis
, 2023 We investigate the impact of coulomb screening on primordial nucleosynthesis in a universe having scale factor that evolves linearly with time. Coulomb screening affects primordial nucleosynthesis via enhancement of thermonuclear reaction rates.

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

Pediatric Blood &Cancer, Volume 71, Issue 11, November 2024.Abstract An attractive flower from the island of Madagascar has in part saved the lives of thousands of children with acute lymphoblastic leukemia (ALL). Random mutations and alterations to the genome led to the evolution of genes encoding enzymes, which would provide the periwinkle flower an arsenal of secondary metabolites to survive within the ...

NEUTRINO EFFECTS IN NUCLEOSYNTHESIS [PDF]
Neutrino Physics, 2001 The nucleosynthesis within a Type II supernova occurs in an intense neutrino flux. I discuss some of the effects associated with neutrino interactions, including direct synthesis in the neutrino process, the role of neutrinos in controlling the r-process path and in postprocessing r-process products, and neutrino oscillation connections.

An Introduction to Primordial Nucleosynthesis
, 2006 International audiencePrimordial nucleosynthesis is one of the three observational evidences for the Big Bang model. Even though they span a range of nine orders of magnitude, there is indeed a good overall agreement between primordial abundances of ^4He,
