Magnetic fields in solar plage regions: insights from high-sensitivity spectropolarimetry
J. M. da Silva Santos, K. Reardon, G. Cauzzi +7
Plage regions are patches of concentrated magnetic field in the Sun's atmosphere where hot coronal loops are rooted. While previous studies have shed light on the properties of pla…
Multi-Height Observations of Atmospheric Gravity Waves at Solar Disk Center
Oana Vesa, Jason Jackiewicz, Kevin Reardon
Atmospheric gravity waves (AGWs) are low-frequency, buoyancy-driven waves that are generated by turbulent convection and propagate obliquely throughout the solar atmosphere. Their…
Ground-based monitoring of the variability of visible Solar spectral lines for improved understanding of solar and stellar magnetism and dynamics
S. Criscuoli, L. Bertello, D. P. Choudhary +7
Long-term high-cadence measurements of stellar spectral variability are fundamental to better understand stellar atmospheric properties and stellar magnetism. These, in turn, are f…
Evaluating Non-LTE Spectral Inversions with ALMA and IBIS
Ryan Hofmann, Kevin Reardon, Ivan Milic +3
We present observations of a solar plage in the millimeter-continuum with the ALMA and in the Ca 8542 and Na 5896 spectral lines with the Interferometric BIdimensional Spectrometer…
Subarcsecond imaging of a solar active region filament with ALMA and IRIS
J. M. da Silva Santos, S. M. White, K. Reardon +4
Quiescent filaments appear as absorption features on the solar disk when observed in chromospheric lines and at continuum wavelengths in the millimeter (mm) range. Active region (A…
IBIS-A: The IBIS data Archive. High resolution observations of the solar photosphere and chromosphere with contextual data
Ilaria Ermolli, Fabrizio Giorgi, Mariarita Murabito +10
The IBIS data Archive (IBIS-A) stores data acquired with the Interferometric BIdimensional Spectropolarimeter (IBIS), which was operated at the Dunn Solar Telescope of the US Natio…
The Effect of Stellar Contamination on Low-resolution Transmission Spectroscopy: Needs Identified by NASA's Exoplanet Exploration Program Study Analysis Group 21
Benjamin V. Rackham, Néstor Espinoza, Svetlana V. Berdyugina +58
Study Analysis Group 21 (SAG21) of NASA's Exoplanet Exploration Program Analysis Group (ExoPAG) was organized to study the effect of stellar contamination on space-based transmissi…
A prototype of a large tunable Fabry-Perot interferometer for solar spectroscopy
V. Greco, A. Sordini, G. Cauzzi +7
Large Fabry-Perot Interferometers are used in a variety of astronomical instrumentation, including spectro-polarimeters for 4-meter class solar telescopes. In this work we comprehe…
Tracing the Chromospheric and Coronal Magnetic Field with AIA, IRIS, IBIS, and ROSA Data
M. J. Aschwanden, K. Reardon, D. Jess
The aim of this study is to explore the suitability of chromospheric images for magnetic modeling of active regions. We use high-resolution images (0.1") from the Interferometric B…
The Source of Three-minute Magneto-acoustic Oscillations in Coronal Fans
D. B. Jess, I. De Moortel, M. Mathioudakis +4
We use images of high spatial, spectral and temporal resolution, obtained using both ground- and space-based instrumentation, to investigate the coupling between wave phenomena obs…
Fabry-Perot versus slit spectropolarimetry of pores and active network. Analysis of IBIS and Hinode data
P. G. Judge, A. Tritschler, H. Uitenbroek +3
We discuss spectropolarimetric measurements of photospheric (Fe I 630.25 nm) and chromospheric (Ca II 854.21 nm) spectral lines. Our long-term goal is to diagnose properties of the…
The solar chromosphere at high resolution with IBIS. IV. Dual-line evidence of heating in chromospheric network
G. Cauzzi, K. P. Reardon, R. J. Rutten +2
The structure and energy balance of the solar chromosphere remain poorly known. We have used the imaging spectrometer IBIS at the Dunn Solar Telescope to obtain fast-cadence, multi…
