Large-scale Vortices in the Solar Photosphere: Statistical Properties and the Reliability of Local Correlation Tracking
Mashael Aldhafeeri, Suzana S. A. Silva, Istvan Ballai +4
Vortices are observed throughout the solar atmosphere, spanning a wide range of spatial scales. Although small-scale vortices have been studied extensively, mesoscale vortices rema…
Detection of the solar internal flows with numerical simulation and machine learning
Hiroyuki Masaki, Hideyuki Hotta
The solar interior is filled with turbulent thermal convection, which plays a key role in the energy and momentum transport and the generation of the magnetic field. The turbulent…
Convective Magnetic Flux Emergence Simulations from the Deep Solar Interior to the Photosphere: Comprehensive Study of Flux Tube Twist
Shin Toriumi, Hideyuki Hotta, Kanya Kusano
The emergence of magnetic flux from the deep convection zone plays an important role in the solar magnetism, such as the generation of active regions and triggering of various erup…
Inversion for Inferring Solar Meridional Circulation: The Case with Constraints on Angular Momentum Transport inside the Sun
Yoshiki Hatta, Hideyuki Hotta, Takashi Sekii
We have carried out inversions of travel times as measured by Gizon et al. (2020) to infer the internal profile of the solar meridional circulation (MC). A linear inverse problem h…
