On the self-consistent model of the axisymmetric radio pulsar magnetosphere

, 1998
We consider a model of axisymmetric neutron star magnetosphere. In our approach, the current density in the region of open field lines is constant and the returning current flows in a narrow layer along the separatrix.

Testing magnetofrictional extrapolation with the Titov-D\'emoulin model of solar active regions

, 2010
We examine the nonlinear magnetofrictional extrapolation scheme using the solar active region model by Titov and D\'emoulin as test field. This model consists of an arched, line-tied current channel held in force-free equilibrium by the potential field ...

Eruptions of Magnetic Ropes in Two Homologous Solar Events on 2002 June 1 and 2: a Key to Understanding of an Enigmatic Flare

, 2009
The goal of this paper is to understand the drivers, configurations, and scenarios of two similar eruptive events, which occurred in the same solar active region 9973 on 2002 June 1 and 2.

Time-dependent full-radius integrated modeling of the DTT tokamak main plasma scenarios

Nuclear Fusion
We use an integrated modeling workflow with the transport code ASTRA coupled with the quasi-linear transport model TGLF-SAT2, the neoclassical model NCLASS, the FACIT model for the neoclassical impurity transport and the IMEP routines for the pedestal ...

Dual characterization of critical fluctuations: Density functional theory & nonlinear dynamics close to a tangent bifurcation

, 2017
We improve on the description of the relationship that exists between critical clusters in thermal systems and intermittency near the onset of chaos in low-dimensional systems.

Impact of spatially varying transport coefficients in EMC3-Eirene simulations of W7-X and assessment of drifts

Nuclear Fusion
Modelling the scrape-off layer of a stellarator is challenging due to the complex magnetic 3D geometry. The here presented study analyses simulations of the scrape-off layer (SOL) of the stellarator Wendelstein 7-X (W7-X) using spatially varying ...

Experiment-modeling studies comparing energy dissipation in the DIII-D SAS and SAS-VW divertors

Nuclear Materials and Energy
Recent DIII-D experiments on Small Angle Slot (SAS) divertors have confirmed that a combination of divertor closure and target shaping can enhance cooling across the divertor target and increase energy dissipation, but with significant dependence on BT ...

Elongation of a Solar Filament and its Three-dimensional Numerical Reconstruction for Magnetic Structures

The Astrophysical Journal
Quiescent filaments are prominent features of the solar atmosphere, and their evolution reflects the coronal magnetic field’s response to photospheric magnetic activity.

Magnetic Reconnection in a Compact Magnetic Dome: Chromospheric Emissions and High-velocity Plasma Flows

The Astrophysical Journal
Magnetic reconnection at small spatial scales is a fundamental driver of energy release and plasma dynamics in the lower solar atmosphere. We present observations of a brightening in an active region, captured in high-resolution data from the Daniel K ...

Two-stage Nature of a Solar Flare with Parallel and Semicircular Ribbons

The Astrophysical Journal
Flare ribbons with parallel and circular morphologies are typically associated with different magnetic reconnection models, and the simultaneous observation of both types in a single event remains rare. Using multiwavelength observations from a tandem of
