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

Onset Mechanism of M6.5 Solar Flare Observed in Active Region 12371
TL;DR: In this article, the authors investigated the sheared arc loops to explore the onset process of the eruptive M6.5 flare using three representative magnetohydrodynamic instabilities: the kink, torus and double arc instabilities (DAI).

Numerical Study of Coronal Mass Ejections, Shocks, and Turbulence: from Chromosphere to 1 AU.
TL;DR: In this article, the authors present a survey of the state-of-the-art tools and techniques used in the development of the HOGA algorithm and its application in the field of artificial intelligence.
Theory of magnetic reconnection in solar and astrophysical plasmas
TL;DR: A review of the current state of understanding of magnetic reconnection can be found in this article, where the authors discuss theoretical results regarding the formation of current sheets in complex three-dimensional magnetic fields and describe the fundamental differences between reconnection in two and three dimensions.

Study of Three-Dimensional Magnetic Structure and the Successive Eruptive Nature of Active Region 12371
TL;DR: In this paper, the authors studied the magnetic structure of successively erupting sigmoid in active region 12371 by modeling the quasi-static coronal field evolution with nonlinear force-free field equilibria.

Design of an adaptable Stokes polarimeter for exploring chromospheric magnetism
TL;DR: The Adaptable ChRomOspheric POLarimeter (ACROPOL) as discussed by the authors is a polarimeter for investigating the chromospheric magnetic field, which consists of a number of lenses, two ferro-electric liquid crystals, a Wollaston prism, and a CCD camera.
