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…
High-resolution Observation of Mini-Filament Eruptions Near Coronal Hole Boundary and Their Response in Solar Corona
Nengyi Huang, Haimin Wang
We investigated mini-filament (MF) eruptions near coronal hole (CH) boundaries to explore their role in coronal dynamics and their potential contributions to the solar wind. Using…
Solar Alfvenic Pulses and Mesoscale Solar Wind
Jeongwoo Lee, Manolis K. Georgoulis, Rahul Sharma +3
Large-scale solar ejections are well understood, but the extent to which small-scale solar features directly influence the solar wind remains an open question, primarily due to the…
MVPinn: Integrating Milne-Eddington Inversion with Physics-Informed Neural Networks for GST/NIRIS Observations
Qin Li, Bo Shen, Haodi Jiang +5
We introduce MVPinn, a Physics-Informed Neural Network (PINN) approach tailored for solving the Milne-Eddington (ME) inversion problem, specifically applied to spectropolarimetric…
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…
