How will DKIST Help Us Understand the Magnetic Connectivity Between the Sun and the Earth?
Abstract
With its 4m aperture and coronagraphic capabilities, the Daniel K Inouye Telescope (DKIST) will revolutionize solar physics. The 4m aperture will enable unprecedented spatial resolutions and polarimetric (i.e., magnetic) sensitivities. DKIST will provide an excellent window into heretofore hardly accessible layers such as the solar chromosphere—the interface layer between the energy reservoir in the photosphere and the hot corona. The corona itself will regularly be observed with the telescope thanks to a set of aperture and focal plane occulters that minimize the direct light from the solar disk. In this manner, access to the off-limb coronal physical conditions, including the magnetic field, velocity flows, and chemical composition will be possible. This new view of the Sun will provide highly improved understanding of the physics behind the processes that magnetically connect the Sun and the Earth, helping us to improve our modeling and predicting capabilities.
