CMEs' Speed, Travel Time, and Temperature: A Thermodynamic Approach

Flandes, Alberto; Lara, Alejandro; Durand-Manterola, Hector J. +2 more

Due to their important role in space weather, coronal mass ejections or CMEs have been thoroughly studied in order to forecast their speed and transit time from the Sun to the Earth. We present a thermodynamic analytical model that describes the dynamics of CMEs. The thermodynamic approach has some advantages with respect to the hydrodynamic appro…
