This paper outlines the current understanding of solar flares, mainly focused on
magnetohydrodynamic (MHD) processes responsible for producing a flare. Observations …

Strong solar flares and coronal mass ejections, here defined not only as the bursts of
electromagnetic radiation but as the entire process in which magnetic energy is released …

We investigate the evolution of NOAA Active Region (AR) 11817 during 2013 August 10–12,
when it developed a complex field configuration and produced four confined, followed by …

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 …

Solar flares and coronal mass ejections, the most catastrophic eruptions in our solar system,
have been known to affect terrestrial environments and infrastructure. However, because …

Hinode is Japan's third solar mission following Hinotori (1981–1982) and Yohkoh (1991–
2001): it was launched on 2006 September 22 and is in operation currently. Hinode carries …

The topology and dynamics of the three-dimensional magnetic field in the solar atmosphere
govern various solar eruptive phenomena and activities, such as flares, coronal mass …

To study the buildup of a magnetic flux rope before a major flare and coronal mass ejection
(CME), we compute the magnetic helicity injection, twist accumulation, and topology …

In this ISSI-supported series of studies on magnetic helicity in the Sun, we systematically
implement different magnetic helicity calculation methods on high-quality solar …

An investigation of helicity injection by photospheric shear motions is carried out for two
active regions (ARs), NOAA 11158 and 11166, using line-of-sight magnetic field …
