Investigation of the dependence of angular momentum transport on spatial scales for construction of differential rotation
K. Mori, H. Hotta
We investigate the dependence of the angular momentum transport (AMT) on the spatial scales with numerical simulation of solar-like stars. It is thought that turbulence has an esse…
Impact of subsurface convective flows on the formation of sunspot magnetic field and energy build-up
Takafumi Kaneko, Hideyuki Hotta, Shin Toriumi +1
Strong solar flares occur in -spots characterized by the opposite-polarity magnetic fluxes in a single penumbra. Sunspot formation via flux emergence from the convection zone to…
Mean-field analysis on large-scale magnetic fields at high Reynolds numbers
Ryota Shimada, Hideyuki Hotta, Takaaki Yokoyama
Solar magnetic fields comprise an 11-year activity cycle, represented by the number of sunspots. The maintenance of such a solar magnetic field can be attributed to fluid motion in…
Generation solar-like differential rotation
H. Hotta, K. Kusano, R. Shimada
We analyze the simulation result shown in Hotta & Kusano, 2021 in which the solar-like differential rotation is reproduced. The Sun is rotating differentially with the fast equator…
