Rebuilding and memory of recurrent-jet magnetic systems

Determine how the coronal magnetic system rebuilds itself after one eruption to produce a subsequent coronal jet, and characterize which magnetic-configuration properties persist and how magnetic energy and helicity are redistributed between successive jets.

Background

The paper studies recurrent coronal jets that originate from the same source region and therefore provide a setting for examining magnetic-field evolution between eruptions. Although magnetic-flux cancellation and emergence have been proposed as drivers, the physical processes that restore an eruption-capable configuration after a jet are not resolved.

The authors explicitly identify the rebuilding of the coronal magnetic system, the persistence of magnetic-configuration properties, and the redistribution of energy and helicity as unresolved questions relevant to explaining how successive jets can arise from the same source region.

References

However, several fundamental questions remain open. For example, how does the coronal magnetic system rebuild itself after one eruption and become capable of producing the next? Which properties of the magnetic configuration persist from one eruption to the next, and how are magnetic energy and helicity redistributed between successive jets?
