We report a THEMIS-D spacecraft crossing of a magnetopause reconnection exhaust ~9 ion skin depths (di) downstream of an X-line. This book covers many aspects of space plasma physics, but is. The second part of this talk reviews discoveries made by MMS in asymmetric diffusion regions at the magnetopause, where reconnection occurs between the shocked solar wind and the magnetospheric plasma. Aspects of asymmetric reconnection are compared to and contrasted with symmetric reconnection.
The final topic discussed now and in Lecture 15 is that of magnetic reconnection at the magnetopause. Suppose that the solar wind magnetic field in Figures and is directed southwards. Since the dipole field lines are directed northwards this situation involves anti-parallel magnetic field lines being brought together by a plasma flow. Our proposed project is to study the magneto reconnection processes in the Earth's magnetosphere by using both analytical methods and computer simulations. The three-dimensional (3-D) topology of the reconnected field lines and the kinetic aspects of magnetic reconnection in the collisionless magnetosphere are emphasized in the present study.

Introduction  Magnetic reconnection is now recognized as the dominant transport mechanism at the magnetopause during periods of southward IMF [Baumjohann and Paschmann, ].However, there exist important gaps in our understanding of the details of how and where reconnection occurs.
One of the critical issues is to identify where the reconnection line on the dayside magnetopause is Cited by: Proton Anisotropies Upstream of the Magnetopause (pages –) S. Peter Gary, Dan Winske, Michael E.
McKean, Stephen A. Fuselier, Richard E. Denton and Brian J. anderson. Magnetic reconnection is the key mechanism that controls input as well as output of energy and momentum in the magnetosphere. The input occurs on the magnetopause. Abstract. Magnetic reconnection at Earth’s dayside magnetopause plays a crucial role in space weather-related phenomena.
The response of the magnetosphere to input from interplanetary space differs greatly depending on where reconnection happens and how efficiently it reconnects magnetic flux from interplanetary by: Previous kinetic simulations for symmetric layers have demonstrated that the flow vortices compress the magnetopause current layer and induce magnetic reconnection, leading to the rapid streaming.
The interconnection of magnetic fields through magnetic reconnection at the magnetopause is the dominant process for mass, energy, and momentum transfers from the Earth's magnetosheath to the Author: Colin Schultz.
This volume provides a comprehensive overview of our current observational knowledge and theoretical understanding of the outer boundary of the Earth's magnetic field: the magnetopause. All mass, momentum, and energy transferred from the solar-wind plasma flow into the geomagnetic cavity must cross the magnetopause.
 We present particle‐in‐cell simulations of collisionless magnetic reconnection in a system (like the magnetopause) with a large density asymmetry across the current layer. In the presence of an ambient component of the magnetic field perpendicular to the reconnection plane the gradient creates a diamagnetic drift that advects the X‐line with the electron diamagnetic by: Kinetic aspects of reconnection at the magnetopause.

No. A10 Generalized Walén tests through Alfvén waves and rotational discontinuities using electron flow velocitiesCited by: We investigate three aspects of magnetic reconnection where kinetic processes play a strong role: hot O+ and cold ion behaviors in magnetopause reconnection, their effect on the reconnection rate, and electron heating during magnetotail reconnection.
At the magnetopause, we analyze observed velocity distribution functions (VDFs) and find that hot O+, despite its large gyroradius, almost fully participates in the reconnection outflow Author: Shan Wang. Diamagnetic Suppression of Component Magnetic Reconnection at the Magnetopause M.

The three upper panels of Fig. 2 show the components of the vector velocity field in the layer-oriented frame. In the upper panel, we show the large change of magnitude of the V x, layer component at the magnetopause (the flow tangential acceleration across the reconnection current sheet), while the other two components of the velocity remain almost by: Magnetic reconnection is a physical process occurring in highly conducting plasmas in which the magnetic topology is rearranged and magnetic energy is converted to kinetic energy, thermal energy, and particle ic reconnection occurs on timescales intermediate between slow resistive diffusion of the magnetic field and fast Alfvénic timescales.

Since the introduction of magnetic reconnection into magnetospheric physics by Dungey /1/, the argument over its existence at the dayside magnetopause has raged back - and - forth. Much indirect evidence for dayside reconnection has been : M.F. Smith.
We have studied magnetopause reconnection using a global 3-D MHD simulation in which the interplanetary magnetic field (IMF) has been set to large positive .Abstract.
We review the current understanding of the dynamics of the Earth’s magnetopause and boundary layers. We describe basic insights and recent advances concerning the main mechanisms that mediate solar wind energy, momentum and plasma transfer into the magnetosphere: magnetic reconnection, the Kelvin–Helmholtz instability and diffusive by: 6.Magnetic reconnection is arguably the most important process regulating the transport of mass, momentum, magnetic flux, and energy from the solar wind into the magnetospheres of the magnetized planets.
Accordingly, there is a long history of research addressing magnetic reconnection at the magnetopause, ranging from early to modern observations, and including kinetic theory and .
