Plasma in Astrophysics [PDF]

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 ...

Formation of dense, electromagnetically accelerated plasma for laboratory astrophysics

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,

Extreme Plasma Astrophysics

, 2019
This is a science white paper submitted to the Astro-2020 and Plasma-2020 Decadal Surveys. The paper describes the present status and emerging opportunities in Extreme Plasma Astrophysics -- a study of astrophysically-relevant plasma processes taking place under extreme conditions that necessitate taking into account relativistic, radiation, and QED ...

Doppler tomography in fusion plasmas and astrophysics [PDF]

, 2015
Doppler tomography is a well-known method in astrophysics to image the accretion flow, often in the shape of thin discs, in compact binary stars. As accretion discs rotate, all emitted line radiation is Doppler-shifted. In fast-ion Dα (FIDA) spectroscopy

Plasma physics of extreme astrophysical environments [PDF]

Reports on Progress in Physics, 2014
Certain classes of astrophysical objects, namely magnetars and central engines of supernovae and gamma-ray bursts (GRBs), are characterized by extreme physical conditions not encountered elsewhere in the Universe. In particular, they possess magnetic fields that exceed the critical quantum field of 44 teragauss.

Fluorescence in Astrophysical Plasmas [PDF]

, 2013
Following the initial detection by Bowen in 1934 of the strong O III linesbeing due to accidental resonance with strong He II radiation, many strong spectralemission lines are explained as produced by fluorescence. Many of these areFe II lines pumped by H Lyα, as a consequence of strong radiation from hydrogenand a favorable energy level structure for ...

Revisiting magnetohydrodynamic modelling of the 2024 total solar eclipse with AI-reconstructed far-side photospheric field data

Astronomy & Astrophysics
Context. Total solar eclipses provide high-quality white-light observations of the solar corona. They also provide valuable reference data for validating global three-dimensional magnetohydrodynamic (MHD) coronal models driven by photospheric magnetic ...
