Triggering of magnetic reconnection in a magnetosheath current sheet due to compression against the magnetopause

摘要: [1] We report in-situ measurements by three THEMIS spacecraft showing the evolution of reconnection in a solar wind current sheet as transited from across bow shock and close to magnetopause on July 11, 2008. The observations suggest that exhaust within was disrupted its interaction with shock, while subsequent compression against significantly reduced both thickness plasma β initiated at new X-line located magnetosheath. Furthermore, electrons were heated center magnetosheath exhaust, contrast previously reported absence electron heating exhausts, but consistent occasionally observed association reconnection. This suggests level exhausts depends strongly boundary conditions.
