Recent Progress in Nuclear Astrophysics
, 1999 The manuscript reviews progress achieved in recent years in various aspects of nuclear astrophysics, including stellar nucleosynthesis, nuclear aspects of supernova collapse and explosion, neutrino-induced reactions and their possible role in the ...

Uncertainties in AGB Evolution and Nucleosynthesis
, 2016 We summarise the evolution and nucleosynthesis in AGB and Super-AGB stars. We then examine the major sources of uncertainty, especially mass-loss.Comment: 8 pages, no figures.

The temperature and chronology of heavy-element synthesis in low-mass stars [PDF]
, 2015 Roughly half of the heavy elements (atomic mass greater than that of iron) are believed to be synthesized in the late evolutionary stages of stars with masses between 0.8 and 8 solar masses. Deep inside the star, nuclei (mainly iron) capture neutrons and

Improved astrophysical rate for the 18O(p,α)15N reaction by underground measurements
Physics Letters B, 2019 The 18O(p,α)15N reaction affects the synthesis of 15N, 18O and 19F isotopes, whose abundances can be used to probe the nucleosynthesis and mixing processes occurring deep inside asymptotic giant branch (AGB) stars.

The Revival of Galactic Cosmic Ray Nucleosynthesis? [PDF]
, 1998 Because of the roughly linear correlation between Be/H and Fe/H in low metallicity halo stars, it has been argued that a ``primary'' component in the nucleosynthesis of Be must be present in addition to the ``secondary'' component from standard Galactic ...

Heavy Element Nucleosynthesis in the Brightest Galactic Asymptotic Giant Branch stars
, 2012 We present updated calculations of stellar evolutionary sequences and detailed nucleosynthesis predictions for the brightest asymptotic giant branch (AGB) stars in the Galaxy with masses between 5Msun to 9Msun, with an initial metallicity of Z =0.02 ([Fe/

Pop III i-process nucleosynthesis and the elemental abundances of SMSS J0313-6708 and the most iron-poor stars [PDF]
, 2017 © 2017 The Author(s). Published by Oxford University Press on behalf of the Royal Astronomical Society. We have investigated a highly energetic H-ingestion event during shell He burning leading to H-burning luminosities of log (L H /L ⊙ ) ~ 13 in a 45M ...

Biochar‐Based Materials for Electrochemical Energy Storage
ChemElectroChem, Volume 13, Issue 9, 5 May 2026.Overview of biochar application in electrochemical energy storage. The global transition toward sustainable energy technologies is reshaping the design principles of electrochemical energy storage systems. Biochar, a tunable, carbon‐rich material derived from biomass, has emerged as a promising platform for next‐generation electrodes due to its ...

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.
