On the Nature of the Three-part Structure of Solar Coronal Mass Ejections
Hongqiang Song, Jie Zhang, Leping Li +4
Coronal mass ejections (CMEs) result from eruptions of magnetic flux ropes (MFRs) and can possess a three-part structure in white-light coronagraphs, including a bright front, dark…
Decoding the Pre-Eruptive Magnetic Field Configurations of Coronal Mass Ejections
S. Patsourakos, A. Vourlidas, T. Török +15
A clear understanding of the nature of the pre-eruptive magnetic field configurations of Coronal Mass Ejections (CMEs) is required for understanding and eventually predicting solar…
Activity Complexes and A Prominent Poleward Surge During Solar Cycle 24
Zi-Fan Wang, Jie Jiang, Jie Zhang +1
Long-lasting activity complexes (ACs), characterised as a series of closely located, continuously emerging solar active regions (ARs), are considered generating prominent poleward…
Do All Interplanetary Coronal Mass Ejections Have A Magnetic Flux Rope Structure Near 1 AU?
Hongqiang Song, Jie Zhang, Xin Cheng +6
Interplanetary coronal mass ejections (ICMEs) often consist of a shock wave, sheath region, and ejecta region. The ejecta regions are divided into two broad classes: magnetic cloud…
Recurring Homologous Solar Eruptions in NOAA AR 11429
Suman K. Dhakal, Jie Zhang, Panditi Vemareddy +1
We present the study of three homologous solar eruptions from NOAA active region (AR) 11429 over four days. This large and complex AR divided into two relatively simple sub-regions…
Eruption of Solar Magnetic Flux Ropes Caused by Flux Feeding
Quanhao Zhang, Yuming Wang, Rui Liu +5
Large-scale solar eruptions are believed to have a magnetic flux rope as the core structure. However, it remains elusive as to how the flux rope builds up and what triggers its eru…
WISPR Imaging of a Pristine CME
Phillip Hess, Alexis Rouillard, Athanasios Kouloumvakos +6
The Wide-field Imager for Solar Probe (WISPR) on board the Parker Solar Probe (PSP) observed a CME on 2018 November 01, the first day of the initial PSP encounter. The speed of the…
Why torus-unstable solar filaments experience failed eruption?
Zhenjun Zhou, Xin Cheng, Jie Zhang +5
To investigate the factors that control the success and/or failure of solar eruptions, we study the magnetic field and 3-Dimensional (3D) configuration of 16 filament eruptions dur…
Mass Loss via Solar Wind and Coronal Mass Ejections During Solar Cycle 23 and 24
Wageesh Mishra, Nandita Srivastava, Yuming Wang +3
Similar to the Sun, other stars shed mass and magnetic flux via ubiquitous quasi-steady wind and episodic stellar coronal mass ejections (CMEs). We investigate the mass loss rate v…
The Origin of Major Solar Activity - Collisional Shearing Between Nonconjugated Polarities of Multiple Bipoles Emerging Within Active Regions
Georgios Chintzoglou, Jie Zhang, Mark C. M. Cheung +1
Active Regions (ARs) that exhibit compact Polarity Inversion Lines (PILs) are known to be very flare-productive. However, the physical mechanisms behind this statistical inference…
On the Propagation of a Geoeffective Coronal Mass Ejection during March 15 -- 17, 2015
Yuming Wang, Quanhao Zhang, Jiajia Liu +11
The largest geomagnetic storm so far in the solar cycle 24 was produced by a fast coronal mass ejection (CME) originating on 2015 March 15. It was an initially west-oriented CME an…
A Statistical Study of the Average Iron Charge Distributions inside Magnetic Clouds for Solar Cycle 23
Hongqiang Song, Ze Zhong, Yao Chen +5
Magnetic clouds (MCs) are the interplanetary counterpart of coronal magnetic flux ropes. They can provide valuable information to reveal the flux rope characteristics at their erup…
Evidence of the Solar EUV hot channel as a magnetic flux rope from remote-sensing and in-situ observations
Hongqiang Song, Yao Chen, Jie Zhang +5
Hot channels (HCs), high temperature erupting structures in the lower corona of the Sun, have been proposed as a proxy of magnetic flux ropes (MFRs) since their initial discovery.…
Predicting the Arrival Time of Coronal Mass Ejections with the Graduated Cylindrical Shell and Drag Force Model
