Synthetic Ca II 8542 Ã Stokes Profile Associated with Chromospheric Magnetic Reconnection in a Simulated Active Region
Xinyu Zhou, Takaaki Yokoyama, Haruhisa Iijima +4
Magnetic reconnection is an important driving mechanism of many chromospheric phenomena, e.g., UV bursts and chromospheric jets. Information about magnetic field is indispensable f…
Comparison of Polar Magnetic Fields Derived from MILOS and MERLIN Inversions with Hinode/SOT-SP Data
Masahito Kubo, Daikou Shiota, Yukio Katsukawa +8
The detailed investigation of the polar magnetic field and its time evolution is one of the major achievements of Hinode. Precise measurements of the polar magnetic field are essen…
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…
Magnetic diffusion in Solar atmosphere produces measurable electric fields
Tetsu Anan, Roberto Casini, Han Uitenbroek +13
The efficient release of magnetic energy in astrophysical plasmas, such as during solar flares, can in principle be achieved through magnetic diffusion, at a rate determined by the…
Persistent Homology analysis for solar magnetograms
Pablo Santamarina Guerrero, Yukio Katsukawa, Shin Toriumi +1
Understanding the magnetic fields of the Sun is essential for unraveling the underlying mechanisms driving solar activity. Integrating topological data analysis techniques into the…
