Mapping the Sun's coronal magnetic field using the Zeeman effect
Thomas A. Schad, Gordon J. D. Petrie, Jeffrey R. Kuhn +9
Regular remote sensing of the magnetic field embedded within the million-degree solar corona is severely lacking. This reality impedes fundamental investigations of the nature of c…
Coronagraphic observations of Si X 1430 nm acquired by DKIST/Cryo-NIRSP with methods for telluric absorption correction
T. A. Schad, A. Fehlmann, G. I. Dima +6
We report commissioning observations of the Si X 1430 nm solar coronal line observed coronagraphically with the Cryogenic Near-Infrared Spectropolarimeter (Cryo-NIRSP) at the Natio…
First Detection of a Strong Magnetic Field on a Bursty Brown Dwarf: Puzzle Solved
S. V. Berdyugina, D. M. Harrington, O. Kuzmychov +4
We report the first direct detection of a strong, 5 kG magnetic field on the surface of an active brown dwarf. LSR J1835+3259 is an M8.5 dwarf exhibiting transient radio and optica…
Calibrating and Stabilizing Spectropolarimeters with Charge Shuffling and Daytime Sky Measurements
David Harrington, J. R. Kuhn, Rebecca Nevin
Well-calibrated spectropolarimetry studies at resolutions of 10,000 with signal-to-noise ratios (SNRs) better than 0.01\% across individual line profiles, are becoming common w…
Investigating the magnetism of brown dwarfs
O. Kuzmychov, S. Berdyugina, D. Harrington +1
We model the spectra of two brown dwarfs observed with the low resolution spectropolarimeter LRIS (Keck observatory) during several rotational phases in order to infer their magnet…
Precision and Resolution in Stellar Spectropolarimetry
D. M. Harrington, J. R. Kuhn
Stellar spectropolarimetry is a relatively new remote sensing tool for exploring stellar atmospheres and circumstellar environments. We present the results of our HiVIS survey and…
