PSP Observations of a Slow Shock Pair Bounding a Large‐Scale Plasmoid/Macro Magnetic Hole

Slow shocks are introduced to be the main dissipation sites in Petschek reconnection model, but they seldom observed interplanetary space. We report a slow shock pair bounding plasmoid/macro magnetic hole by Parker Solar Probe. The jump conditions across examined and confirmed satisfy Rankine-Hugoniot relations. flow speed preshock postshock regions of both match up with characteristics shocks. is suggested part curved plasmoid produced reconnection. Our findings append new site picture energy conversion through solar wind In addition, results suggest that plasmoids emitted local reconnections could possible origin macro holes wind.
