First measurement of the 7Li(D, n) astrophysical S-factor in laser-induced full plasma

Physics Letters B, 2023
Nuclear fusion reactions which produce energies and most of the elements in the Universe are the keys to driving the process of the Big Bang nucleosynthesis, as well as the evolution of stars.

Dense astrophysical plasmas [PDF]

Journal of Physics: Condensed Matter, 2002
We briefly examine the properties of dense plasmas characteristic of the atmospheres of neutron stars and of the interior of massive white dwarfs. These astrophysical bodies are natural laboratories to study respectively the problem of pressure ionization of hydrogen in a strong magnetic field and the crystallization of the quantum one-component-plasma

RelSIM: A Relativistic Semi-implicit Method for Particle-in-cell Simulations

The Astrophysical Journal Supplement Series, 2023
We present a novel Relativistic Semi-Implicit Method (RelSIM) for particle-in-cell (PIC) simulations of astrophysical plasmas, implemented in a code framework ready for production runs. While explicit PIC methods have gained widespread recognition in the

Plasma code for astrophysical charge exchange emission at X-ray wavelengths [PDF]

, 2016
Charge exchange X-ray emission provides unique insights into the interactions between cold and hot astrophysical plasmas. Besides its own profound science, this emission is also technically crucial to all observations in the X-ray band, since charge ...

Fe xvii X-RAY LINE RATIOS FOR ACCURATE ASTROPHYSICAL PLASMA DIAGNOSTICS [PDF]

, 2011
New laboratory measurements using an electron beam ion trap and an X-ray microcalorimeter are presented for the n = 3 to n = 2 Fe xvii emission lines in the 15–17 Å range, along with new theoretical predictions for a variety of electron energy ...

He-like Ions as Practical Astrophysical Plasma Diagnostics: From Stellar Coronae to Active Galactic Nuclei [PDF]

, 2010
We review X-ray plasma diagnostics based on the line ratios of He-like ions. Triplet/singlet line intensities can be used to determine electronic temperature and density, and were first developed for the study of the solar corona.

Temperature‐Dependent Kinetics of Plasma‐Based CO2 Conversion: Interplay of Electron‐Driven and Thermal‐Driven Chemistry

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.

The Screening Characteristics of the Dense Astrophysical Plasmas: The Three-Component Systems

Atoms, 2017
As the object of investigation, astrophysical fully ionized electron-ion plasma is chosen with positively charged ions of two different kinds, including the plasmas of higher non-ideality.

Suprathermal Soliton Solutions to Nonlinear Schrödinger Equation

Contributions to Plasma Physics, EarlyView.
ABSTRACT Maxwell distributions are very difficult to find in the low‐pressure environment far away the Earth atmosphere, permeated by high temperatures, various types of radiation, highly energetic particles, space debris, and subjected to microgravity, presenting crucial challenges for spacecraft design and operations, and affecting astronaut's health.

Net lithium deposition and dominant self-sputtering in lithium tokamak experiment-β with a liquid lithium wall

Nuclear Materials and Energy
We observed enhanced net lithium deposition and lithium erosion, possibly dominated by physical sputtering of lithium by lithium-ion bombardment, on the outer plasma-facing surface in the Lithium Tokamak eXperiment-β (LTX-β) during liquid lithium wall ...
