Coronal 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 کاملThe Composition of Interplanetary Coronal Mass Ejections
Interplanetary coronal mass ejection (ICME) associated plasma can exhibit signatures in elemental, ionic and isotopic composition. These signatures occur in less than 50% of all ICMEs, but are very indicative of ICME plasma. We review these compositional anomalies and briefly discuss a physical scenario that could be responsible for these anoma-
متن کاملLow polarised emission from the core of coronal mass ejections
Aims. In white-light coronagraph images, cool prominence material is sometimes observed as bright patches in the core of coronal mass ejections (CMEs). If, as generally assumed, this emission is caused by Thomson-scattered light from the solar surface, it should be strongly polarised tangentially to the solar limb. However, the observations of a CME made with the SECCHI/STEREO coronagraphs on 3...
متن کاملInitiation and propagation of coronal mass ejections
This paper reviews recent progress in the research on the initiation and propagation of CMEs. In the initiation part, several trigger mechanisms are discussed; In the propagation part, the observations and modelings of EIT waves/dimmings, as the EUV counterparts of CMEs, are described.
