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…
Principles Of Heliophysics: a textbook on the universal processes behind planetary habitability
Karel Schrijver, Fran Bagenal, Tim Bastian +59
Heliophysics is the system science of the physical connections between the Sun and the solar system. As the physics of the local cosmos, it embraces space weather and planetary hab…
{\it f}-mode interactions with thin flux tubes: the scattering matrix
S. M. Hanasoge, A. C. Birch, T. J. Bogdan +1
We calculate the scattering effects associated with the interaction of a surface gravity or {\it f} mode with a thin magnetic flux tube embedded in a realistically stratified mediu…
Spectropolarimetric inversions of the Ca II 8498 A and 8542 A lines in the quiet Sun
A. Pietarila, H. Socas-Navarro, T. Bogdan
We study non-LTE inversions of the Ca II infrared triplet lines as a tool for inferring physical properties of the quiet Sun. The inversion code is successful in recovering the tem…
Spectropolarimetric observations of the Ca II 8498 A and 8542 A lines in the quiet Sun
A. Pietarila, H. Socas-Navarro, T. Bogdan
The Ca II infrared triplet is one of the few magnetically sensitive chromospheric lines available for ground-based observations. We present spectropolarimetric observations of the…
