Modelling the total solar eclipse in 2024 with COCONUT

Astronomy & Astrophysics
Context. Coronal modelling is crucial for a better understanding of solar physics and heliophysics. Accurate plasma conditions at the outer boundary of a solar corona lead to more precise space weather predictions.

Optimized gyrosynchrotron algorithms and fast codes [PDF]

, 2010
Gyrosynchrotron (GS) emission of charged particles spiraling in magnetic fields plays an exceptionally important role in astrophysics. In particular, this mechanism makes a dominant contribution to the continuum solar and stellar radio emissions. However,

Multithermal Jet Formation Triggered by Flux Emergence

The Astrophysical Journal Letters, 2023
Flux emergence is responsible for various solar eruptions. Combining observation and simulations, we investigate the influence of flux emergence at one footpoint of an arcade on coronal rain as well as induced eruptions.

Analysis of one- and two-particle spectra at RHIC based on a hydrodynamical model [PDF]

, 2002
We calculate the one-particle hadronic spectra and correlation functions of pions based on a hydrodynamical model. Parameters in the model are so chosen that the one-particle spectra reproduce experimental results of $\sqrt{s}=130A$GeV Au+Au collisions ...

Non-thermal electron acceleration in turbulent, post-flare coronal loops

Astronomy & Astrophysics
Context. The generation of energetic, non-thermal electrons during solar flares plays a critical role in energy transportation from the corona to the chromosphere, producing regions of observed intense X-ray emission.

Automatic Classification of Plasma Regions in Near-Earth Space With Supervised Machine Learning: Application to Magnetospheric Multi Scale 2016–2019 Observations

Frontiers in Astronomy and Space Sciences, 2020
The proper classification of plasma regions in near-Earth space is crucial to perform unambiguous statistical studies of fundamental plasma processes such as shocks, magnetic reconnection, waves and turbulence, jets and their combinations.

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,
