TLDR
In this paper, the expansion instability of a toroidal current ring in low-beta magnetized plasma is investigated, and the results are verified with experiments on spheromak expansion and with essential properties of solar coronal mass ejections.Abstract:
The expansion instability of a toroidal current ring in low-beta magnetized plasma is investigated. Qualitative agreement is obtained with experiments on spheromak expansion and with essential properties of solar coronal mass ejections, unifying the two apparently disparate classes of fast and slow coronal mass ejections.read more

Origin and structures of solar eruptions I: Magnetic flux rope
Xin Cheng,Yang Guo,Mingde Ding +2 more
TL;DR: In this paper, the origin and early structures of coronal mass ejections (CMEs) and solar flares are discussed from a multi-wavelength observational perspective, with the aim of improving the prediction of the occurrence of CMEs/flares and their effects on geospace and the heliosphere.
Journal ArticleDOI
Filament Kinking and Its Implications for Eruption and Re-formation
TL;DR: In this paper, the authors investigate the relationship between the kinking motions of a filament and its success or failure to erupt, and present an analysis of kinking in filaments and its implications for other filament phenomena.

Magnetic Properties of Solar Active Regions that Govern Large Solar Flares and Eruptions
TL;DR: In this paper, the authors systematically survey all flare events with GOES levels of >=M5.0 within 45 deg from disk center between May 2010 and April 2016, and show that even X-class events do not require delta-sunspots or strong-field, high-gradient polarity inversion lines.

A Comparative Study of Confined and Eruptive Flares in NOAA AR 10720
TL;DR: In this article, the authors investigate the distinct properties of two types of flares: eruptive flares associated with coronal mass ejections (CMEs) and confined flares without CMEs, and demonstrate that the strength and the decay index of the background magnetic field may determine whether or not a flare is eruptive or not.
