Bidirectional Plasma Jets Driven by Magnetic Reconnection: Observations by GST and SDO

Haisheng Ji, Jianping Li, Jinhua Shen, Shuai Gu, Xu Yang, Yangyu Liu

Observations confirm bidirectional plasma jets arise from magnetic reconnection between rising filamentary threads and overlying horizontal loops.

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

These observations confirm that the bidirectional plasma jets can be generated by magnetic reconnection between the rising filamentary threads or material and the overlying horizontal magnetic loops.

C2weakest assumption

The interpretation that the observed timing difference (304 Å brightening ~30 s before Hα for the first jet) and spatial location at polarity inversion lines and umbra-penumbra boundary directly locate the reconnection site in the transition region and establish the causal link to the jets.

C3one line summary

New GST and SDO observations of bidirectional plasma jets in a sunspot link them to magnetic reconnection triggered by rising filamentary material interacting with horizontal magnetic loops.
