WebFeb 1, 2024 · The Hall-MHD fluid model is found to reproduce kinetic reconnection rates only for a sufficiently strong guide field, for which ion inertia breaks the frozen-in condition and the outflow becomes Alfvénic in the kinetic system. ... the ions do not respond to the reconnection dynamics leading to “electron-only” reconnection with very large ... Webof reconnection in space, i.e., electron-only reconnection in the ion-scale current sheet, which is different from the traditional magnetic reconnection model, and challenges the …
Electron‐Only Magnetic Reconnection: Lessons …
Webelectron-only reconnection. The essential physical result is that if the initial collapsing solution is not sufficiently anisotropic when its thickness is above the ion scales, the collapse continues down to a thickness well below the ion scale, and electron-only reconnection will occur. Remarkably (considering the formal limitation of KREHM to WebNov 16, 2024 · In electron-only reconnection, ions do not have enough space to couple to the newly reconnected magnetic fields, suppressing ion jet formation and resulting in thinner sub-proton-scale current ... update msbuild to latest version
