Analytical Solution of the Hanle Effect in View of CLASP and Future Polarimetric Solar Studies
We have solved a problem of the Hanle effect for the hydrogen Lyman- α line in an intuitive and straightforward way. The Stokes parameters amid an anisotropic radiation field and a magnetic field are derived as an analytical formula which ...
