    Post-AGB Stars as Tracers of AGB Nucleosynthesis: An Update by Devika Kamath, Hans Van Winckel

    Published 2022-04-01
    “…Observations from post-asymptotic giant branch (post-AGB) stars serve as exquisite tools to quantify and understand AGB nucleosynthesis. In this contribution, we review the invaluable constraints provided by post-AGB stars with which to study AGB nucleosynthesis, especially the slow neutron capture nucleosynthesis (i.e., the <i>s</i>-process).…”

    Big Bang Nucleosynthesis hunts chameleon dark matter by Hua Chen, Taishi Katsuragawa, Shinya Matsuzaki, Taotao Qiu

    Published 2020-02-01
    “…Abstract We study the chameleon field dark matter, dubbed scalaron, in F (R) gravity in the Big Bang Nucleosynthesis (BBN) epoch. With an R 2-correction term required to solve the singularity problem for F (R) gravity, we first find that the scalaron dynamics is governed by the R 2 term and the chameleon mechanism in the early universe, which makes the scalaron physics model-independent regarding the low-energy scale modification. …”

    Compatibility of big bang nucleosynthesis in some modified gravities by Abdul Malik Sultan, Abdul Jawad

    Published 2022-10-01
    “…Abstract This paper is devoted to investigate the implications of Einstein-Aether and modified Hořava–Lifshitz theories of gravity to the formation of light elements in the early universe named as big bang nucleosynthesis. We choose different models from these theories for a detailed investigation of big bang nucleosynthesis epoch and compare it with the observational bounds. …”
