Solar wind parameters play a dominant role in reconnection rate, which controls the solar wind-magnetosphere coupling efficiency at Earth’s magnetopause. Besides, low-energy ions from the ionosphere, frequently detected on the magnetospheric side of the magnetopause, also affect magnetic reconnection. However, the specific role of low-energy ions in reconnection is still an open question under active discussion. In the present work, we report in situ observations of a multiscale, multi-type…

Plasma and Energetic Particle Behaviors During Asymmetric Magnetic Reconnection at the Magnetopause
The factors controlling asymmetric reconnection and the role of the cold plasma population in the reconnection process are two outstanding questions. We present a case study of multipoint Cluster
Hot magnetospheric O+ and cold ion behavior in magnetopause reconnection: Cluster observations
In reconnection, the presence of heavy ions like O+ increases the ion mass density reducing the fluid's Alfven speed. In addition, it may modify the reconnection structure, which can also change the
Modification of the Hall physics in magnetic reconnection due to cold ions at the Earth's magnetopause
Magnetic reconnection is a process permitting mass and energy exchange across plasma boundaries and converting magnetic energy into particle kinetic energy. Strong electric fields and currents due to
Observations of the step-like accelerating processes of cold ions in the reconnection layer at the dayside magnetopause
Abstract Cold ions of plasmaspheric origin have been observed to abundantly appear in the magnetospheric side of the Earth’s magnetopause. These cold ions could affect the magnetic reconnection
Electron magnetic reconnection without ion coupling in Earth’s turbulent magnetosheath
Observations of electron-scale current sheets in Earth’s turbulent magnetosheath reveal electron reconnection without ion coupling, contrary to expectations from the standard model of magnetic reconnection.
Electron-scale measurements of magnetic reconnection in space
Nasa's Magnetospheric Multiscale mission is used to probe the plasma properties within a reconnection event in Earth's magnetosphere, and finds that the process is driven by the electron-scale dynamics.
Dayside flow bursts in the Earth's outer magnetosphere
[1] Observations from the Polar/Thermal Ion Dynamics Experiment indicate the presence of cold magnetospheric/ionospheric H+, He+, and a trace of O+ in the vicinity of the subsolar magnetopause during
Magnetospheric Multiscale Overview and Science Objectives
Magnetospheric Multiscale (MMS), a NASA four-spacecraft constellation mission launched on March 12, 2015, will investigate magnetic reconnection in the boundary regions of the Earth’s magnetosphere,
Electron-Scale Quadrants of the Hall Magnetic Field Observed by the Magnetospheric Multiscale spacecraft during Asymmetric Reconnection.
It is concluded that the spacecraft directly passed through the inner electron diffusion region based on the violation of the electron frozen-in condition, the energy dissipation, and the slippage between the electron flow and the magnetic field.
Dependence of the dayside magnetopause reconnection rate on local conditions
We estimate the reconnection rates for eight dayside magnetopause reconnection events observed by the Cluster spacecraft and compare them with the predictions of the Cassak-Shay Formula (Rcs) Cassak
