The Driver of Coronal Mass Ejections in the Low Corona: A Flux Rope

X. Cheng, J. Zhang, D. M. Ding +2

Recent Solar Dynamic Observatory observations reveal that coronal mass ejections (CMEs) consist of a multi-temperature structure: a hot flux rope and a cool leading front (LF). The…

Multi-point shock and flux rope analysis of multiple interplanetary coronal mass ejections around 2010 August 1 in the inner heliosphere

C. Möstl, C. J. Farrugia, E. K. J. Kilpua +20

We present multi-point in situ observations of a complex sequence of coronal mass ejections (CMEs) which may serve as a benchmark event for numerical and empirical space weather pr…

Study of the 3D Coronal Magnetic Field of Active Region 11117 Around the Time of a Confined Flare Using a Data-Driven CESE--MHD Model

Chaowei Jiang, Xueshang Feng, S. T. Wu +1

We apply a data-driven MHD model to investigate the three-dimensional (3D) magnetic field of NOAA active region (AR) 11117 around the time of a C-class confined flare occurred on 2…

Interpretation of the coronal magnetic field configuration of the Sun

Bo Li, Xing Li, Hui Yu

The origin of the heliospheric magnetic flux on the Sun, and hence the origin of the solar wind, is a topic of hot debate.While the prevailing view is that the solar wind originate…

A New Code for Nonlinear Force-Free Field Extrapolation of the Global Corona

Chaowei Jiang, Xueshang Feng, Changqing Xiang

Reliable measurements of the solar magnetic field are still restricted to the photosphere, and our present knowledge of the three-dimensional coronal magnetic field is largely base…

Effects of Thomson-Scattering Geometry on White-Light Imaging of an Interplanetary Shock: Synthetic Observations from Forward Magnetohydrodynamic Modelling

Ming Xiong, J. A. Davies, M. M. Bisi +3

Stereoscopic white-light imaging of a large portion of the inner heliosphere has been used to track interplanetary coronal mass ejections. At large elongations from the Sun, the wh…

Radio signatures of CME-streamer interaction and source diagnostics of type II radio burst

S. W. Feng, Y. Chen, X. L. Kong +4

It has been suggested that type II radio bursts are due to energetic electrons accelerated at coronal shocks. Radio observations, however, have poor or no spatial resolutions to pi…

A broken solar type II radio burst induced by a coronal shock propagating across the streamer boundary

Xiang-Liang Kong, Yao Chen, Gang Li +4

We discuss an intriguing type II radio burst that occurred on 2011 March 27. The dynamic spectrum was featured by a sudden break at about 43 MHz on the well-observed harmonic branc…

A New Implementation of the Magnetohydrodynamics-Relaxation Method for Nonlinear Force-Free Field Extrapolation in the Solar Corona

Chaowei Jiang, Xueshang Feng

Magnetic field in the solar corona is usually extrapolated from photospheric vector magnetogram using a nonlinear force-free field (NLFFF) model. NLFFF extrapolation needs a consid…

Characteristics of kinematics of a coronal mass ejection during the 2010 August 1 CME-CME interaction event

Manuela Temmer, Bojan Vrsnak, Tanja Rollett +16

We study the interaction of two successive coronal mass ejections (CMEs) during the 2010 August 1 events using STEREO/SECCHI COR and HI data. We obtain the direction of motion for…

Interactions between Coronal Mass Ejections Viewed in Coordinated Imaging and In Situ Observations

Ying D. Liu, Janet G. Luhmann, Christian Mostl +7

The successive coronal mass ejections (CMEs) from 2010 July 30 - August 1 present us the first opportunity to study CME-CME interactions with unprecedented heliospheric imaging and…
