Joachim Vogt,B. Zieger,B. Zieger,Karl-Heinz Glassmeier,A. Stadelmann,May-Britt Kallenrode,Miriam Sinnhuber,Holger Winkler +7 more
TL;DR: In this paper, scaling relations for cutoff energies and differential particle fluxes during periods of reduced dipole moment are derived for high rigidity galactic cosmic ray particles in the GV range and to lower rigidity solar energetic particles.

The dependence of the coupled magnetosphere‐ionosphere‐thermosphere system on the Earth's magnetic dipole moment
TL;DR: In this article, the authors used simulations with the Coupled Magnetosphere-Ionosphere-Thermosphere model to investigate how the magnetosphere, upper atmosphere, and solar quiet (Sq) geomagnetic variation respond as the Geomagnetic dipole moment M varies between 2⋅10 22 and 10⋆10 22 Am 2.

TL;DR: In this paper, the response of the magnetosphere-ionosphere-thermosphere system to a 25% reduction in magnetic field intensity, using the coupled magnetosphere ionosphere thermalmosphere (CMIT) model, was studied.

Modeling the Young Sun's Solar Wind and its Interaction with Earth's Paleomagnetosphere
TL;DR: In this paper, the authors present a focused parameter study of solar wind-magnetosphere interaction for the young Sun and Earth, ∼3.5 Gyr ago, that relies on magnetohydrodynamic (MHD) simulations for both the solar wind and the magnetosphere.

Scaling relations in the paleomagnetosphere derived from MHD simulations
TL;DR: In this paper, a series of numerical magnetohydrodynamic (MHD) simulations of axial dipolar paleomagnetospheres, gradually decreasing the relative dipole moment from 1 to 0.1, was carried out to test the validity of the theoretical scaling relations for different values of the north-south interplanetary magnetic field component (IMF B z ).

Regular Article: A Solution-Adaptive Upwind Scheme for Ideal Magnetohydrodynamics
TL;DR: In this article, the authors present a computational scheme for compressible magnetohydrodynamics (MHD) based on the same elements that make up many modern compressible gas dynamics codes: high-resolution upwinding based on an approximate Riemann solver for MHD and limited reconstruction; an optimally smoothing multi-stage time-stepping scheme; and solution-adaptive refinement and coarsening.

Magnetopause shape as a bivariate function of interplanetary magnetic field Bz and solar wind dynamic pressure
Edmond C. Roelof,David G. Sibeck +1 more
TL;DR: In this article, the shape of the magnetopause was determined as a bivariate function of the hourly averaged solar wind dynamic pressure (p) and the north-south component of the interplanetary magnetic field (IMF) B(sub z).

TL;DR: In this article, a 3D numerical ideal magnetohydrodynamics (MHD) model is presented to describe the time-dependent expulsion of a coronal mass ejection (CME) from the solar corona propagating to 1 astronomical unit (AU) using the Block Adaptive Tree Solar-Wind Roe Upwind Scheme (BATS-RUS) code.

TL;DR: In this article, a new compressible MHD model for simulating the three-dimensional structure of the solar wind under steady state conditions is presented, where the initial potential magnetic field is reconstructed throughout the computational volume using the source surface method, in which the necessary boundary conditions for the field are provided by solar magnetogram data.
