Coronal mass ejections (CMEs) are large-scale magnetized plasma structures ejected from the Sun with speeds ranging from a few to more than 2000 kilometers per second. The CMEs impart energy and momentum to planetary atmospheres and magnetospheres. CMEs also drive fast mode magnetohydrodynamic shocks, which in turn accelerate electrons and ions. Experimental and theoretical research is conducted to investigate various aspects of CMEs from their initiation at the Sun, their interplanetary propagation, and the subsequent impact on various heliospheric structures. These studies also include the shock-driving capability of CMEs, as derived from the interplanetary radio emission associated with these solar eruptions. Spacecraft data obtained by white-light coronagraphs and radio instruments are used for these investigations. Emphasis is placed on space weather studies that relate the properties of CMEs to the intensity of geomagnetic storms and solar energetic particle events.
