Design study of a HPGe detector array for β-decay investigation in laboratory ECR plasmas
Frontiers in Physics, 2022 In the frame of the PANDORA project, a new experimental approach aims at measuring in-plasma β-decay rate as a function of thermodynamical conditions of the environment, namely a laboratory magnetized plasma able to mimic some stellar-like conditions ...

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 & AstrophysicsIn 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).

Atoms, 2023 The nucleosynthesis of chemical elements has been established to be the result of a variety of different types of nuclear reactions in stars. Under the extreme temperatures and densities encountered in such environments, nuclear isomers can be populated ...

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.

The stellar origins of 96Zr excesses in presolar graphites from the Murchison meteorite
Astronomy & AstrophysicsContext. Zirconium-96 is a stable isotope that can be synthesized under different neutron-rich nucleosynthetic conditions. Astrophysical models predict its production to occur in various stellar environments: from low-to-intermediate-mass asymptotic ...

Universe, 2021 The slow neutron-capture process (s-process) efficiency in low-mass AGB stars (1.5 < M/M⊙ < 3) critically depends on how mixing processes in stellar interiors are handled, which is still affected by considerable uncertainties.

THE SLOW DEATHS FROM CLIMATE CHANGE: A Planetary View from Papua New Guinea
Cultural Anthropology, Volume 41, Issue 1, Page 57-81, February 2026.ABSTRACT How do we tell the stories of climate change? This essay explores the slow violence and death experienced by marginalized, racialized, indigenous bodies as climate change differentially impacts communities across the globe. Paying attention to locations beyond the spectacular events that have come to be associated with climate change, the ...

Universe, 2022 The foundations of stellar nucleosynthesis have been established more than 70 years ago. Since then, much progress has been made, both on the theoretical side, with stellar evolution and nucleosynthesis models of increasing complexity, using more and ...

No crisis for big bang nucleosynthesis [PDF]
Physical Review D, 1996 Contrary to a recent claim, the inferred primordial abundances of the light elements are quite consistent with the expectations from standard big bang nucleosynthesis when attention is restricted to direct observations rather than results from chemical evolution models.
