Origin of line broadening in fading granule: influence of small-scale turbulence
Ryohtaroh T. Ishikawa, Yukio Katsukawa
In the quiet region of the solar photosphere, turbulent convective motions of the granular flows naturally drive the subgranular-scale flows. However, evaluating such small-scale v…

Solar horizontal flow evaluation using neural network and numerical simulation with snapshot data
Hiroyuki Masaki, Hideyuki Hotta, Yukio Katsukawa +1
We suggest a method that evaluates the horizontal velocity in the solar photosphere with easily observable values using a combination of neural network and radiative magnetohydrody…
