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…
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.…
Effects of spectral resolution on simple magnetic field diagnostics of the Mg II h & k lines
Rebecca Centeno, Matthias Rempel, Roberto Casini +1
We study the effects of finite spectral resolution on the magnetic field values retrieved through the weak field approximation (WFA) from the cores of the Mg II h & k lines. The re…
Ultraviolet Spectropolarimetry With Polstar: Using Polstar to test Magnetospheric Mass-loss Quenching
M. E. Shultz, R. Casini, M. C. M. Cheung +17
Polstar is a proposed NASA MIDEX space telescope that will provide high-resolution, simultaneous full-Stokes spectropolarimetry in the far ultraviolet, together with low-resolution…
Ultraviolet Spectropolarimetry: Investigating stellar magnetic field diagnostics
C. P. Folsom, R. Ignace, C. Erba +9
Magnetic fields are important for stellar photospheres and magnetospheres, influencing photospheric physics and sculpting stellar winds. Observations of stellar magnetic fields are…
TIC: A Stokes inversion code for scattering polarization with partial frequency redistribution and arbitrary magnetic fields
H. Li, T. del Pino Alemán, J. Trujillo Bueno +1
We present the Tenerife Inversion Code (TIC), which has been developed to infer the magnetic and plasma properties of the solar chromosphere and transition region via full-Stokes i…
