Study of Chromospheric Global-Scale Flows using Local Correlation Tracking Across the past 10 Solar Cycles
Qin Li, Yan Xu, Keiji Hayashi +2
Global-scale solar surface flows, including differential rotation and meridional circulation, provide key observational constraints on the solar dynamo. We investigate these flows…
Large Magnetic Flux Rope Formation in an X2.1 Flare observed on September 6, 2011
Arpita Roddanavar, Satoshi Inoue, Keiji Hayashi +3
Solar active region 11283 produced an X2.1 flare associated with a solar eruption on September 6, 2011. Observations revealed a preflare sigmoidal structure and a circular flare ri…
A Data-constrained Magnetohydrodynamic Simulation of Successive X-class Flares in Solar Active Region 13842. II. Dynamics of the Solar Eruption Associated with the X9.0 Solar Flare
Keitarou Matsumoto, Satoshi Inoue, Keiji Hayashi +5
Active region NOAA 13842 produced two successive solar flares: an X7.1-class flare on October 1, 2024, and an X9.0-class flare on October 3, 2024. This study continues our previous…
Acceleration of Solar Eruptions via Enhanced Torus Instability Driven by Small-Scale Flux Emergence
Satoshi Inoue, Takahiro Miyoshi, Keiji Hayashi +4
Despite decades of research, the fundamental processes involved in the initiation and acceleration of solar eruptions remain not fully understood, making them long-standing and cha…
A Data-constrained Magnetohydrodynamic Simulation of Successive X-class Flares in Solar Active Region 13842 I. Dynamics of the Solar Eruption Associated with the X7.1 Solar Flare
Keitarou Matsumoto, Satoshi Inoue, Nian Liu +3
We investigated the initiation and the evolution of an X7.1-class solar flare observed in solar active region NOAA 13842 on October 1, 2024, based on a data-constrained magnetohydr…
Simulations of Global Solar Convection with a Fully Compressible CHORUS++ Code
Keiji Hayashi, Alexander G. Kosovichev, Chunlei Liang
Fluid-dynamics simulations of global solar convection are a critically important tool for assessing the dynamics of the solar interior. However, simulation studies with a fully com…
