Hbeta Spicules, Small-scale Jets, and Hbeta Microflashes: Sub-arcsecond Dynamic Events and their Magnetic Origins in the Lower Solar Chromosphere Observed by DKIST
Navdeep K. Panesar, V. Aparna, Sanjiv K. Tiwari +3
We examine an on-disk solar quiet region of enhanced magnetic network using Hbeta images from Daniel K. Inouye Solar Telescopes (DKISTs) Visible Broadband Imager (VBI) and line-of-…
Exploring if a coronal dimming event can produce coronal hole-like properties
Adriana De-Sassi, Louise Harra, Krzysztof Barczynski +8
Coronal dimmings, or transient coronal holes, are manifested as a sudden reduction in extreme ultraviolet (EUV) and X-ray emission, often following solar eruptions. We investigate…
Potential Solar Precursors to Magnetic Switchbacks
Durgesh Tripathi, Maria S. Madjarska, Judy Karpen +9
The origin of magnetic switchbacks-large-amplitude, spherically polarized magnetic-field fluctuations with local polarity inversions shown to be nearly ubiquitous in the inner heli…
Extreme Ultraviolet Microflashes at Plume Bases: A Candidate for Powering the Corona and Solar Wind?
Navdeep K. Panesar, Sanjiv K. Tiwari, Meng Jin +4
Solar plumes - outflows of bright coronal plasma - are a major component of the open-magnetic-field corona and solar wind, but their driving mechanism remains uncertain. Here we re…
Turbulence and its Potential Impact on Solar Chromospheric and Coronal Heating
Gary P. Zank, Xiaocan Li, Krishna Khanal +8
Low-frequency turbulence in the solar chromosphere remains poorly understood. We address 1) the sources of low-frequency turbulence that potentially heat the chromosphere, and 2) h…
Magnetic switchback formation: a review of proposed mechanisms
Peter F. Wyper, Jonathan Squire, Etienne Pariat +19
Magnetic switchbacks are large amplitude deflections of the magnetic field within the solar wind. They are Alfvénic in character and so are associated with a spike in velocity and…
The Making of Delta Sunspots
Ronald L. Moore, Sanjiv K. Tiwari, V. Aparna +2
We explore what fraction of delta sunspots in which the polarity inversion line (PIL) is sharp in photospheric magnetograms are made from a writhe kink in an emerging twisted flux…
Observations of a Twin Pair of Atypical Solar Flares and a Magnetic-reconnection Scenario
Satyam Agarwal, Alphonse C. Sterling, Shibu K. Mathew +3
We present observations and a magnetic-reconnection scenario of a twin pair of "atypical flares" that occurred on 2022 April 22 in a quadrupolar magnetic configuration formed by tw…
Formation of chromospheric fan-shaped jets through magnetic reconnection
Annu Bura, Tanmoy Samanta, Avijeet Prasad +4
Recurrent chromospheric fan-shaped jets highlight the highly dynamic nature of the solar atmosphere. They have been named as ''light walls'' or ''peacock jets'' in high-resolution…
Unveiling the Dynamics and Genesis of Small-scale Fine Structure Loops in the Lower Solar Atmosphere
Annu Bura, Tanmoy Samanta, Alphonse Sterling +4
Recent high-resolution solar observations have unveiled the presence of small-scale loop-like structures in the lower solar atmosphere, often referred to as unresolved fine structu…
Transition Region Brightenings in a Moss Region and their Relation with Lower Atmospheric Dynamics
Bhinva Ram, Tanmoy Samanta, Yajie Chen +5
Small-scale Brightenings (SBs) are commonly observed in the transition region that separates the solar chromosphere from the corona. These brightenings, omnipresent in active regio…
Generation of Solar Spicules and Subsequent Atmospheric Heating
Tanmoy Samanta, Hui Tian, Vasyl Yurchyshyn +9
Spicules are rapidly evolving fine-scale jets of magnetized plasma in the solar chromosphere. It remains unclear how these prevalent jets originate from the solar surface and what…
