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…
