英文摘要 | We analyzed 20 reconnection events observed by the Magnetosphere MultiScale mission, finding that in a subregion of the magnetospheric inflow, the electron temperature parallel to the magnetic field (T-e||) decreases toward the separatrix with increasing densities. Such T-e|| variation is not consistent with the heating through the parallel potential mechanism for magnetospheric electrons. Associated with the change in T-e||, low-energy gyrotropic magnetosheath-like electrons are observed. These electrons may come from the magnetosheath, penetrate to the magnetospheric side possibly due to waves in the lower hybrid frequency range, and do not experience as much energization as those from deeper in the magnetosphere. In addition, as T-e|| decreases, the high-energy field-aligned phase-space densities decrease or fluctuate significantly over time. Wave-particle interaction might produce energy conversion and cause the high-energy phase-space density variations. |
