Abstract:Context. Measuring small-scale magnetic fields and constraining their role in energy transport and dynamics in the solar atmosphere are crucial, yet challenging, tasks in solar physics. To this aim, observations of scattering polarization and the Hanle effect in various spectral lines are increasingly used to complement traditional magnetic field determination techniques. Aims. One of the strongest scattering polarization signals in the photosphere is measured in the Sr i line at 4607.3 Å when observed close t… Show more
