Solar horizontal flow evaluation using neural network and numerical simulations with snapshot data

Katsukawa, Yukio; Ishikawa, Ryohtaroh T.; Masaki, Hiroyuki +1 more

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 magnetohydrodynamics simulations. All three-component velocities of thermal convection on the solar surface have important roles in generating waves in the upper atmosphere. However, …

Investigating the magnetic field of the quiet Sun internetwork

Ichimoto, Kiyoshi; Deng, Yuanyong; Shaltout, Abdelrazek M. K. +1 more

We analyze the magnetism of the quiet Sun internetwork (IN) using high-spatial-resolution data obtained by the spectropolarimeter (SP) of the Solar Optical Telescope aboard the Hinode satellite near the disk center of the Sun. The SP data were inverted using the Stokes Inversion based on Response functions (SIR) inversion code with a single-compon…
