Diagnosing the solar atmosphere through the Mg I b2 5173 Å line: II. Morphological classification of the intensity and circular polarization profiles

Context. The Mg I b2 line at 5173 Å is primarily magnetically sensitive to heights between the mid photosphere and the low chromosphere, a region that has not been sufficiently explored in the solar atmosphere but is crucial for understanding the magnetic coupling between the two layers. New generat...

Sumario:Context. The Mg I b2 line at 5173 Å is primarily magnetically sensitive to heights between the mid photosphere and the low chromosphere, a region that has not been sufficiently explored in the solar atmosphere but is crucial for understanding the magnetic coupling between the two layers. New generation solar observatories, both space-borne and ground-based, are now performing polarimetric observations of this spectral line, enabling simultaneous measurements with multiple spectral lines. This allows for detailed studies of the magnetism around the temperature minimum region of the solar atmosphere at high spatial, temporal, and spectral resolutions.
