Estimation of a coronal mass ejection magnetic field strength using radio observations of gyrosynchrotron radiation

Carley, Eoin P.; Vilmer, Nicole; Simões, Paulo J. A. +1 more

Coronal mass ejections (CMEs) are large eruptions of plasma and magnetic field from the low solar corona into interplanetary space. These eruptions are often associated with the acceleration of energetic electrons which produce various sources of high intensity plasma emission. In relatively rare cases, the energetic electrons may also produce gyr…

Context. The magnetic field plays a dominant role in the solar irradiance variability. Determining the contribution of various magnetic features to this variability is important in the context of heliospheric studies and Sun-Earth connection.
Aims: We studied the solar irradiance variability and its association with the underlying magnetic fi…
