Coronal Mass Ejections

Annual Review of Astronomy and Astrophysics, 1984
Sudden expulsions of dense clouds of plasma from the outer atmosphere of the Sun, termed "coronal mass ejections" (CMEs), are the focus of intense observational and theoretical efforts. CMEs are a type of coronal transient, the general name given the disruption of coronal structure.

Coronal mass ejections

AIP Conference Proceedings, 2000
The most dramatic changes in the solar corona occur during coronal mass ejections, or CMEs, during which solar material is propelled outward into the heliosphere from regions in the corona not previously participating in the solar wind expansion. These ejections often produce major solar wind disturbances, large geomagnetic storms, enhancements of ...

Radio Signatures of Coronal Mass Ejection Interaction: Coronal Mass Ejection Cannibalism?

The Astrophysical Journal, 2001
We report the first detection at long radio wavelengths of interaction between coronal mass ejections (CMEs) in the interplanetary medium. The radio signature is in the form of intense continuum-like radio emission following an interplanetary type II burst. At the time of the radio enhancement, coronagraphic images show a fast CME overtaking a slow CME.

Coronal mass ejections

Reviews of Geophysics, 1987
While the first coronal mass ejections (CMEs) were observed with the OSO‐7 white light coronagraph (Tousey, 1973), it was the Skylab coronagraph observations that clearly established CMEs as an important component of solar coronal physics. CMEs have been defined by Hundhausen et al.

Coronal Mass Ejections

1999
Coronal mass ejections are seen as bright features that move outward through the solar corona at speeds from 10 to about 2,000 km s-1. They involve the expulsion of substantial quantities of plasma from large regions of the corona. The spectacular nature of the largest mass ejections is illustrated in Figure 5.1 by a time sequence of four images ...

Coronal mass ejections and interplanetary shocks

Journal of Geophysical Research: Space Physics, 1985
A comparison between Solwind observations of coronal mass ejections (CME's) and Helios 1 observations of interplanetary shocks during 1979–1982 indicates that 72% of the shocks were associated with large, low‐latitude mass ejections on the nearby limb.

Forces governing coronal mass ejections

Advances in Space Research, 2006
Kinematics of CMEs is analyzed to get an insight into the properties of forces partaking in the eruption. It is demonstrated that the Lorentz force plays a dominant role within a distance of a few solar radii. In the distance range 1– 30 solar radii, the inferred values of the Lorentz-force acceleration aL on average decrease with the ...
