A new radiative cooling curve based on an up-to-date plasma emission code

KM Schure, D Kosenko, JS Kaastra, R Keppens… - Astronomy & …, 2009 - aanda.org
This work presents a new plasma cooling curve that is calculated using the SPEX package.
We compare our cooling rates to those in previous works, and implement the new cooling …

[BOEK][B] Advanced magnetohydrodynamics: with applications to laboratory and astrophysical plasmas

JP Goedbloed, R Keppens, S Poedts - 2010 - books.google.com

Accretion funnels onto weakly magnetized young stars

N Bessolaz, C Zanni, J Ferreira, R Keppens… - Astronomy & …, 2008 - aanda.org
Aims. We re-examine the conditions required to steadily deviate an accretion flow from a
circumstellar disc into a magnetospheric funnel flow onto a slow rotating young forming star.…

Magnetized accretion-ejection structures: 2.5-dimensional magnetohydrodynamic simulations of continuous ideal jet launching from resistive accretion disks

F Casse, R Keppens - The Astrophysical Journal, 2002 - iopscience.iop.org
We present numerical magnetohydrodynamic (MHD) simulations of a magnetized accretion
disk launching trans-Alfvénic jets. These simulations, performed in a 2.5-dimensional time-…

MPI-AMRVAC 3.0: Updates to an open-source simulation framework

Context. Computational astrophysics nowadays routinely combines grid-adaptive capabilities
with modern shock-capturing, high resolution spatio-temporal integration schemes in …

Three-dimensional magnetohydrodynamic simulations of the Crab nebula

O Porth, SS Komissarov… - Monthly Notices of the …, 2013 - academic.oup.com
In this paper, we give a detailed account of the first three-dimensional (3D) relativistic
magnetohydrodynamic simulations of pulsar wind nebulae, with parameters most suitable for the …

Adaptive mesh refinement for conservative systems: multi-dimensional efficiency evaluation

R Keppens, M Nool, G Tóth, JP Goedbloed - Computer Physics …, 2003 - Elsevier
Obtainable computational efficiency is evaluated when using an Adaptive Mesh Refinement
(AMR) strategy in time accurate simulations governed by sets of conservation laws. For a …

Growth and saturation of the Kelvin–Helmholtz instability with parallel and antiparallel magnetic fields

R Keppens, G Tóth, RHJ Westermann… - Journal of Plasma …, 1999 - cambridge.org
We investigate the Kelvin–Helmholtz instability occurring at the interface of a shear-flow
configuration in 2D compressible magnetohydrodynamics (MHD). The linear growth and the …
