Separatrix regions of magnetic reconnection at the magnetopause [PDF]

Annales Geophysicae, 2009
Using data from the four Cluster spacecraft we study the separatrix regions of magnetic reconnection sites at the dayside magnetopause under conditions when reconnection is occurring in the magnetopause current layer which separates magnetosheath ...

Sub‐Structures of the Separatrix Region During Magnetic Reconnection

Geophysical Research Letters, 2022
Utilizing data from the Magnetospheric Multiscale mission, the sub‐structures of the separatrix region during reconnection are investigated. A small current system in the separatrix region is embedded in the large Hall current system, which appears as a ...

Separatrix crossing and symmetry breaking in NLSE-like systems due to forcing and damping [PDF]

Nonlinear dynamics, 2020
We theoretically and experimentally examine the effect of forcing and damping on systems that can be described by the nonlinear Schrödinger equation (NLSE), by making use of the phase-space predictions of the three-wave truncation.

Role of the separatrix density in the pedestal performance in deuterium low triangularity JET-ILW plasmas and comparison with JET-C

Nuclear Fusion, 2021
A reduction of the pedestal pressure with increasing separatrix density over pedestal density (n e sep/n e ped) has been observed in JET. The physics behind this correlation is investigated. The correlation is due to two distinct mechanisms. The increase

Magnetic Reconnections in the Presence of Three-Dimensional Magnetic Nulls and Quasi-Separatrix Layers [PDF]

Solar Physics, 2020
Three-dimensional (3D) magnetohydrodynamic simulations are carried out to explore magnetic reconnections in the presence of 3D magnetic nulls and quasi-separatrix layers (QSLs).

Separatrix divergence of stellar streams in galactic potentials [PDF]

Monthly notices of the Royal Astronomical Society, 2020
Flattened axisymmetric galactic potentials are known to host minor orbit families surrounding orbits with commensurable frequencies. The behaviour of orbits that belong to these orbit families is fundamentally different than that of typical orbits with

Construction of the planar vector fields with nonsimple critical point of prescribed topological structure

Современная математика: Фундаментальные направления, 2022
The problem of constructing n-linear (n 2) plane vector elds with isolated critical point and given separatrices of prescribed types is considered. Such constructions are based on the use of vector algebra, the qualitative theory of second-order dynamic ...

Bifurcations in a Leslie-Gower type predator-prey model with a rational non-monotonic functional response

Mathematical Modelling and Analysis, 2022
A Leslie-Gower type predator-prey model including group defense formation is analyzed. This phenomenon, described by a non-monotonic function originates interesting dynamics; positiveness, boundedness, permanence of solutions, and existence of up to ...
