Magnetic reconnection is a multi-faceted process of energy conversion in astrophysical,
space and laboratory plasmas that operates at microscopic scales but has macroscopic …

Solar eruptions are well-recognized as major drivers of space weather but what causes
them remains an open question. Here we show how an eruption is initiated in a non …

Context. Solar active region (AR) 12673 in 2017 September produced the two largest flares
in Solar Cycle 24: the X9. 3 flare on September 6 and the X8. 2 flare on September 10. Aims …

We present a clear case study on the occurrence of two successive X-class flares, including
a decade-class flare (X9. 3) and two coronal mass ejections (CMEs) triggered by shearing …

This paper reviews the studies of solar photospheric magnetic field evolution in active
regions and its relationship to solar flares. It is divided into two topics, the magnetic structure …

We study the physical mechanism of a major X-class solar flare that occurred in the super
NOAA active region (AR) 12192 using data-driven numerical magnetohydrodynamic (MHD) …

Due to the absence of direct measurement, the magnetic field in the solar corona is usually
extrapolated from the photosphere in a numerical way. At the moment, the nonlinear force …

It is well-known that magnetic fields dominate the dynamics in the solar corona, and new
generation of numerical modeling of the evolution of coronal magnetic fields, as featured …

Context. Magnetic helicity has the remarkable property of being a conserved quantity of
ideal magnetohydrodynamics (MHD). Therefore, it could be used as an effective tracer of the …

Solar eruptions are the leading driver of space weather and it is vital for space weather
forecasting to benefit from a comprehensive understanding of the conditions in which solar …
