Solar Mini-Dimming Kinematics and Their Positive Correlations with Coronal Mass Ejections and Prominence
Solar mini-dimmings can be detect in the Extreme Ultra-Violet coronal eruptions. Here, sequences of 171_A images taken by Solar Dynamic Observatory/Atmospheric Imaging Assembaly on 13 June 2010 are used. In this special day, both of coronal mass ejection and prominence were observed. The average velocities and accelerations of 500 mini-dimmings which were detected using on feature based classif...
متن کاملCoronal Mass Ejections
A coronal mass ejection (CME) is an eruption of billions of tonnes of magnetically charged plasma from a star’s corona. The material ejected is sent into interplanetary space where it eventually dissipates. Should the material collide with a planet then that planet’s electro-magnetic field would be temporarily disrupted. If the Earth’s electro-magnetic field were disrupted by a large CME then p...

متن کاملComposition of Coronal Mass Ejections
We analyze the physical origin of plasmas that are ejected from the solar corona. To address this issue, we perform a comprehensive analysis of the elemental composition of interplanetary coronal mass ejections (ICMEs) using recently released elemental composition data for Fe, Mg, Si, S, C, N, Ne, and He as compared to O and H. We find that ICMEs exhibit a systematic abundance increase of eleme...
متن کاملInitiation of Coronal Mass Ejections in a Global Evolution Model
Loss of equilibrium of magnetic flux ropes is a leading candidate for the origin of solar coronal mass ejections (CMEs). The aim of this paper is to explore to what extent this mechanism can account for the initiation of CMEs in the global context. A simplified MHD model for the global coronal magnetic field evolution in response to flux emergence and shearing by large-scale surface motions is ...
