On single point plasma diagnostics in the solar corona using the DKIST

Magnetic-dipole transitions in the visible and infrared provide spectropolarimetric signatures of the plasma properties within the solar corona, including diagnostics for temperature, density, and, uniquely, the magnetic field. The soon-to-be commissioned US National Science Foundation's Daniel K Inouye Solar Telescope offers an unprecedented opportunity for large aperture coronagraphic polarimetry of the solar corona. This work discusses our current knowledge of the polarized line formation in the corona and outlines new and developing methods relevant to achieving single point remote sensing of the coronal properties using the DKIST. We will present updated techniques for multi-line inversions of the magnetic field vector and atomic level alignments, which may be achievable using multi-spectral DKIST first-light instrumentation, as well as the use of single line observations of linear polarization to infer coronal electron densities.
