Slippage of Jets Explained by the Magnetic Topology of NOAA Active Region 12035

TL;DR

This study investigates the origin and behavior of eleven solar jets in NOAA AR 12035, linking their slippage to complex magnetic topology involving null points and quasi-separatrix layers, using multi-instrument observations.

Contribution

It provides the first detailed analysis connecting jet slippage to magnetic topology features like null points and QSLs in NOAA AR 12035.

Findings

Jets moved south at 100-360 km/s

Flux emergence and cancellation influenced jet activity

Jet merging observed between two sites

Abstract

In this study, we present the investigation of eleven recurring solar jets originated from two different sites (site 1 and site 2) close to each other (~ 11 Mm) in the NOAA active region (AR) 12035 during 15--16 April 2014. The jets were observed by the Atmospheric Imaging Assembly (AIA) telescope onboard the Solar Dynamics Observatory (SDO) satellite. Two jets were observed by the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, India telescope in H-alpha. On 15 April flux emergence is important in site 1 while on 16 April flux emergence and cancellation mechanisms are involved in both sites. The jets of both sites have parallel trajectories and move to the south with a speed between 100 and 360 km/s. We observed some connection between the two sites with some transfer of brightening. The jets of site 2 occurred during the second day and have a tendency to move towards the jets of site 1 and merge with them. We conjecture that the slippage of the jets could be explained by the complex topology of the region with the presence of a few low-altitude null points and many quasi-separatrix layers (QSLs), which could intersect with one another.
