Non-thermal Sources from Stereoscopic Hard X-ray and Earth-based Microwave Observations in a Data-Constrained Magnetohydrodynamic Simulation
Keitarou Matsumoto, Satoshi Inoue, Meiqi Wang +5
We analyze the X7.1 flare on 2024 October 1 from NOAA AR 13842 using hard X-ray (HXR) imaging, microwave observations by the Expanded Owens Valley Solar Array (EOVSA), and a three-…
Stereoscopic Observations of Solar X-ray Sources Explained by a Data-Constrained Magnetohydrodynamic Simulation
Keitarou Matsumoto, Satoshi Inoue, Meiqi Wang +6
We investigated the three-dimensional (3D) magnetic structures and dynamics responsible for particle acceleration in an X7.1-class flare that occurred on October 1, 2024, in NOAA a…
Driving mechanisms of solar active region geysers: The role of interacting magnetic flux
Aabha Monga, Satoshi Inoue, Jeongwoo Lee +2
Active region recurrent jets are manifestations of episodic magnetic energy release processes driven by complex interactions in the lower solar atmosphere. While magnetic flux emer…
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…
