The deformation of an erupting magnetic flux rope in a confined solar flare
Ruisheng Zheng, Yihan Liu, Liang Zhang +7
Magnetic flux ropes (MFRs), sets of coherently twisted magnetic field lines, are believed as core structures of various solar eruptions. Their evolution plays an important role to…
Evolution of Magnetic Helicity in Solar Cycle 24
Valery V. Pipin, Alexei A. Pevtsov, Yang Liu +1
We propose a novel approach to reconstruct the surface magnetic helicity density on the Sun or sun-like stars. The magnetic vector potential is determined via decomposition of vect…
Roles of photospheric motions and flux emergence in the major solar eruption on 2017 September 6
Rui Wang, Ying D. Liu, J. Todd Hoeksema +2
We study the magnetic field evolution in the active region (AR) 12673 that produced the largest solar flare in the past decade on 2017 September 6. Fast flux emergence is one of th…
Investigating the Magnetic Imprints of Major Solar Eruptions with SDO/HMI High-Cadence Vector Magnetograms
Xudong Sun, J. Todd Hoeksema, Yang Liu +2
The solar active region photospheric magnetic field evolves rapidly during major eruptive events, suggesting appreciable feedback from the corona. Previous studies of these "magnet…
A Circular-ribbon Solar Flare Following an Asymmetric Filament Eruption
Chang Liu, Na Deng, Rui Liu +6
The dynamic properties of flare ribbons and the often associated filament eruptions can provide crucial information on the flaring coronal magnetic field. This Letter analyzes the…
The Coronal Global Evolutionary Model: Using HMI Vector Magnetogram and Doppler Data to Model the Buildup of Free Magnetic Energy in the Solar Corona
George H. Fisher, William. P. Abbett, David J. Bercik +11
The most violent space weather events (eruptive solar flares and coronal mass ejections) are driven by the release of free magnetic energy stored in the solar corona. Energy can bu…
