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 the Lorentz Force and Torque of Solar Photospheric Emerging Magnetic Fields
Aiying Duan, Chaowei Jiang, Shin Toriumi +1
Magnetic flux generated and intensified by the solar dynamo emerges into the solar atmosphere, forming active regions (ARs) including sunspots. Existing theories of flux emergence…
Comparative Study of Data-driven Solar Coronal Field Models Using a Flux Emergence Simulation as a Ground-truth Data Set
Shin Toriumi, Shinsuke Takasao, Mark C. M. Cheung +4
For a better understanding of magnetic field in the solar corona and dynamic activities such as flares and coronal mass ejections, it is crucial to measure the time-evolving corona…
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…
Various Local Heating Events in the Earliest Phase of Flux Emergence
Shin Toriumi, Yukio Katsukawa, Mark C. M. Cheung
Emerging flux regions (EFRs) are known to exhibit various sporadic local heating events in the lower atmosphere. To investigate the characteristics of these events, especially to l…
Magnetic Properties of Solar Active Regions that Govern Large Solar Flares and Eruptions
Shin Toriumi, Carolus J. Schrijver, Louise K. Harra +2
Solar flares and coronal mass ejections (CMEs), especially the larger ones, emanate from active regions (ARs). With the aim to understand the magnetic properties that govern such f…
