Alfven waves in the solar corona.
Steven Tomczyk,Scott W. McIntosh,Stephen L. Keil,Philip G. Judge,Thomas A. Schad,D. H. Seeley,J. Edmondson +6 more
TL;DR: In this paper, the authors reported the detection of Alfven waves in intensity, line-of-sight velocity, and linear polarization images of the solar corona taken using the FeXIII 1074.7-nanometer coronal emission line with the Coronal Multi-Channel Polarimeter (CoMP) instrument at the National Solar Observatory, New Mexico.
Alfven Waves in the Solar Corona
Steven Tomczyk,Scott W. McIntosh,Stephen L. Keil,Philip G. Judge,Thomas A. Schad,D. H. Seeley,J. Edmondson +6 more
TL;DR: An estimate of the energy carried by the waves that are spatially resolved indicates that they are too weak to heat the solar corona; however, unresolved Alfvén waves may carry sufficient energy.

TL;DR: The National Science Foundation's Daniel K. Inouye solar telescope (DKIST) as discussed by the authors provides the highest-resolution observations of the Sun ever achieved with a 4-m aperture.
Journal ArticleDOI
He I VECTOR MAGNETOMETRY OF FIELD-ALIGNED SUPERPENUMBRAL FIBRILS
TL;DR: In this paper, high-resolution spectropolarimetric observations of superpenumbral fibrils in the He I triplet with sufficient polarimetric sensitivity to infer their full magnetic field geometry are presented.
