The impact of limited time resolution on the forward-scattering polarization in the solar Sr I 4607 Å line

no code implementations • 21 Jan 2021 • T. del Pino Alemán, J. Trujillo Bueno

Theoretical investigations predicted that high spatio-temporal resolution observations in the Sr I 4607 A line must show a conspicuous scattering polarization pattern at the solar disk-center, which encodes information on the unresolved magnetism of the inter-granular photospheric plasma.
