Derivation of Instrument Requirements for Polarimetry using Mg, Fe, and Mn lines between 250 and 290 nm
A. G. de Wijn, P. G. Judge, R. Ezzeddine +1
Judge et al. (2021) recently argued that a region of the solar spectrum in the near-UV between about 250 and 290 nm is optimal for studying magnetism in the solar chromosphere due…
First Observation of Chromospheric Waves in a Sunspot by DKIST/ViSP: The Anatomy of an Umbral Flash
Ryan J. French, Thomas J. Bogdan, Roberto Casini +2
The Visible Spectro-Polarimeter (ViSP) of the NSF Daniel K. Inouye Solar Telescope (DKIST) collected its Science Verification data on May 7-8, 2021. The instrument observed multipl…
The enduring mystery of the solar corona
Philip G. Judge
Physicists have long known that the Sun's magnetic fields make its corona much hotter than the surface of the star itself. But how -- and why -- those fields transport and deposit…
Optimal spectral lines for measuring chromospheric magnetic fields
P. Judge, P. Bryans, R. Casini +4
This paper identifies spectral lines from X-ray to infrared wavelengths which are optimally suited to measuring vector magnetic fields as high as possible in the solar atmosphere.…
Thermal and Non-Thermal Properties of Active Region Recurrent Coronal Jets
Alin R. Paraschiv, Alina C. Donea, Philip G. Judge
We present observations of recurrent active region coronal jets and derive their thermal and non-thermal properties, by studying the physical properties of the plasma simultaneousl…
The mercurial Sun at the heart of our solar system
Philip Gordon Judge
As the powerhouse of our solar system, the Sun's electromagnetic planetary influences appear contradictory. On the one hand, the Sun for aeons emitted radiation which was "just rig…
