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…
Solar differential rotation reproduced with high-resolution simulation
H. Hotta, K. Kusano
The Sun rotates differentially with a fast equator and slow pole. Convection in the solar interior is thought to maintain the differential rotation. However, although many numerica…
Relationship between magnetic field properties and statistical flow using numerical simulation and magnetic feature tracking on solar photosphere
K. Takahata, H. Hotta, Y. Iida +1
We perform radiative magnetohydrodynamic calculations for the solar quiet region to investigate the dependence of statistical flow on magnetic properties and the three-dimensional…
Formation of super-strong horizontal magnetic field in delta-type sunspot in radiation magnetohydrodynamic simulations
H. Hotta, S. Toriumi
We perform a series of radiative magnetohydrodynamic simulations to understand the amplification mechanism of the exceptionally strong horizontal magnetic field in delta-type sunsp…
On rising magnetic flux tube and formation of sunspots in a deep domain
H. Hotta, H. Iijima
We investigate the rising flux tube and the formation of sunspots in an unprecedentedly deep computational domain that covers the whole convection zone with a radiative magnetohydr…
Spontaneous Generation of delta-sunspots in Convective Magnetohydrodynamic Simulation of Magnetic Flux Emergence
Shin Toriumi, Hideyuki Hotta
Observations reveal that strong solar flares and coronal mass ejections tend to occur in complex active regions characterized by delta-sunspots, spot rotation, sheared polarity inv…
