Coronal Mass Ejections and their Associated Radio Emissions
Abstract
Coronal mass ejections (CMEs) are important drivers of processes in the interplanetary medium and the near- Earth environment, including shocks, CMEs, and geomagnetic disturbances. Radio observations of CMEs and associated phenomena offer a number of unique diagnostics of CMEs and their environment in the nascent stages of their development. These include thermal free-free radiation, nonthermal synchrotron radiation, and plasma radiation. These emissions can be used to constrain the plasma properties of CMEs - including the plasma density and magnetic field - as they propagate outward from the Sun. Under certain conditions, they can probe the response of the corona to the CME. Some recent and suggestive observations are presented of radio emission from CMEs, as well as of associated radio bursts.
