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…

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…
