Magnetic flux emergence from the solar convection zone into the overlying atmosphere is
the driver of a diverse range of phenomena associated with solar activity. In this article, we …

Coronal mass ejections (CMEs) and solar flares are the large-scale and most energetic
eruptive phenomena in our solar system and able to release a large quantity of plasma and …

Nonlinear force-free field (NLFFF) models are thought to be viable tools for investigating the
structure, dynamics, and evolution of the coronae of solar active regions. In a series of …

Magnetic flux ropes are characterized by coherently twisted magnetic field lines, which are
ubiquitous in magnetized plasmas. As the core structure of various eruptive phenomena in …

In this paper, we address the formation of a magnetic flux rope (MFR) that erupted on 2012
July 12 and caused a strong geomagnetic storm event on July 15. Through analyzing the …

Eruptions, flares, and coronal mass ejection (CMEs) are due to physical phenomena mainly
driven by an initially force-free current-carrying magnetic field. We review some key …

A clear understanding of the nature of the pre-eruptive magnetic field configurations of
Coronal Mass Ejections (CMEs) is required for understanding and eventually predicting …

We present a formation process of a filament in active region NOAA 12574 during the period
from 2016 August 11 to 12. Combining the observations of the Global Oscillation Network …

Solar flares and coronal mass ejections are the most powerful explosions in the Sun. They
are major sources of potentially destructive space weather conditions. However, the …

Context. A filament channel (FC), a plasma volume where the magnetic field is primarily
aligned with the polarity inversion line, is believed to be the pre-eruptive configuration of …
