Formation of dense, electromagnetically accelerated plasma for laboratory astrophysics [PDF]

EPJ Web of Conferences, 2013
We proposed tapered pinch discharge as a measure to conduct laboratory astrophysics experiments. Basic behaviors of the plasma have been characterized using a prototype device. Results show that the plasma flux and velocity depend on initial gas density,

Introduction to plasma astrophysics characteristics of astrophysical plasma high density plasma.

Kakuyūgō kenkyū, 1989
Property of High Density Matter with density from 1g/cm3 to 1016g/cm3 is argued. Using the equation of state for high density matter, the equilibrium structure of high density star is discussed. There are two phases of high density stars. They are white dwarf and neutron star. Each has a maximum possible mass.

Plasma in astrophysics

Physica Scripta, 1982
Two examples of plasma phenomena of importance to astrophysics are reviewed. These are examples where astrophysical understanding hinges on further progress in plasma physics understanding. The two examples are magnetic reconnection and the collisionless interaction between a population of energetic particles and a cooler gas or plasma, in particular ...

Investigation of Machine Learning Techniques for Disruption Prediction Using JET Data

Plasma, 2023
Disruption prediction and mitigation is of key importance in the development of sustainable tokamak reactors. Machine learning has become a key tool in this endeavour. In this paper, multiple machine learning models are tested and compared.

Non-Linear Damping of Surface Alfvén Waves Due to Uniturbulence

Frontiers in Astronomy and Space Sciences, 2022
This investigation is concerned with uniturbulence associated with surface Alfvén waves that exist in a Cartesian equilibrium model with a constant magnetic field and a piece-wise constant density.

COCONUT, a Novel Fast-converging MHD Model for Solar Corona Simulations. III. Impact of the Preprocessing of the Magnetic Map on the Modeling of the Solar Cycle Activity and Comparison with Observations

The Astrophysical Journal, 2023
We developed a novel global coronal COCONUT (Coolfluid Corona Unstructured) model based on the COOLFluiD code. The steady-state model is predetermined by magnetograms set as boundary conditions, while inside the numerical domain the corona is described ...

Analysis of Deformation and Erosion during CME Evolution

Geosciences, 2021
Magnetised coronal mass ejections (CMEs) are quite substantially deformed during their journey form the Sun to the Earth. Moreover, the interaction of their internal magnetic field with the magnetic field of the ambient solar wind can cause deflection ...

COCONUT, a Novel Fast-converging MHD Model for Solar Corona Simulations. II. Assessing the Impact of the Input Magnetic Map on Space-weather Forecasting at Minimum of Activity

The Astrophysical Journal, 2023
This paper is dedicated to the new implicit unstructured coronal code COCONUT, which aims at providing fast and accurate inputs for space-weather forecasting as an alternative to empirical models.
