Electron Heat Flux and Whistler Instability in the Earth's Magnetosheath

Alexandros Chasapis, Emiliya Yordanova, Giulia Cozzani, Ida Svenningsson, Mats Andr\'e, Steven J. Schwartz, Yuri V. Khotyaintsev

The electron heat flux in the magnetosheath is shaped by the draped magnetic field and limited by whistler instability thresholds.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We find that the heat flux is shaped by the magnetosheath magnetic field as it drapes around the magnetosphere. ... Also, the heat flux is limited by whistler instability thresholds.

C2weakest assumption

That local magnetosheath processes do not substantially modify the heat flux, which depends on the ability to cleanly separate upstream solar wind effects from local ones in the data.

C3one line summary

Electron heat flux in the magnetosheath is shaped by magnetic field draping, increases with field strength, and is limited by whistler instability thresholds.
