Nucleosynthesis in O-Ne-Mg Supernovae [PDF]

, 2007
We have studied detailed nucleosynthesis in the shocked surface layers of an oxygen-neon-magnesium core collapse supernova with an eye to determining whether the conditions are suitable for r-process nucleosynthesis.

Massive Star Modeling and Nucleosynthesis

Frontiers in Astronomy and Space Sciences, 2021
After a brief introduction to stellar modeling, the main lines of massive star evolution are reviewed, with a focus on the nuclear reactions from which the star gets the needed energy to counterbalance its gravity.

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 ...

Primordial nucleosynthesis

, 2017
International audiencePrimordial nucleosynthesis, or big bang nucleosynthesis (BBN), is one of the three evidences for the big bang model, together with the expansion of the universe and the cosmic microwave background.

A study of U Aquarii and the nucleosynthesis of neutrons and S-process elements in evolved stars of low mass [PDF]

, 2014
The origin of the extreme hydrogen deficiency observed in the R Coronae Borealis (RCrB) stars remains poorly understood. A likely mechanism for producing this deficiency is one whereby the original hydrogen envelope of the star is engulfed and ...

The Nuclear Astrophysics program at n_TOF (CERN)

EPJ Web of Conferences, 2017
An important experimental program on Nuclear Astrophysics is being carried out at the n_TOF since several years, in order to address the still open issues in stellar and primordial nucleosynthesis.

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model

Systems Research and Behavioral Science, Volume 43, Issue 3, Page 1212-1228, May/June 2026.
ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Asymmetrical thermonuclear supernovae triggered by the tidal disruption of white dwarfs

Astronomy & Astrophysics
In a dense star cluster core, a tidal disruption event (TDE) of a white dwarf (WD) can occur if the WD passes within the tidal radius of an intermediate-mass black hole (IMBH).

Neutron-Driven Nucleosynthesis in Stellar Plasma

Frontiers in Physics, 2022
A large uncertainty for the slow neutron capture nucleosynthesis (s-process) models is caused by the amount of neutrons available to the process itself.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

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.
