The dynamics of the observed solar granulation: spatio-temporal variations of line of sight velocity and thermodynamic parameters
We investigated the dynamics of solar granulation, using the neutral iron line λ ≈ 639.3 nm profiles from highspatial resolution observations around the centre of the solar disc, in the non-perturbed region. We reproduced spatio-temporal variations of kinematic and thermodynamic parameters of solar...
