TL;DR
This study reports the observation of small, fast-moving bright plasma blobs ejected from a sunspot light bridge, analyzing their kinematics, energetics, and possible formation mechanisms using IRIS and SDO data.
Contribution
It provides the first detailed analysis of small-scale bright blobs from a sunspot light bridge, including their velocities, energies, and potential formation processes.
Findings
Average blob speed: 71.7 km/s
Blob temperature: ~10^5.47 K
Estimated kinetic energy: 10^22.8 erg
Abstract
Light bridges (LBs) are bright lanes that divide an umbra into multiple parts in some sunspots. Persistent oscillatory bright fronts at a temperature of K are commonly observed above LBs in the 1400/1330 \AA~passbands of the Interface Region Imaging Spectrograph (IRIS). Based on IRIS observations, we report small-scale bright blobs from the oscillating bright front above a light bridge. Some of these blobs reveal a clear acceleration, whereas the others do not. The average speed of these blobs projected onto the plane of sky is km s, with an initial acceleration of km s. These blobs normally reach a projected distance of 3--7 Mm from their origin sites. From the transition region images we find an average projected area of Mm for the blobs. The blobs were also detected in multi-passbands of the Solar Dynamics…
