Kinematics Of Coronal Mass Ejections Between 2 And 30 Solar Radii - What Can Be Learned About Forces Governing The Eruption?

Kinematics of more than 5000 coronal mass ejections (CMEs) measured in the distance range 2-30 solar radii is investigated. A distinct anticorrelation between the acceleration, a, and the velocity, v, is found. In the linear form, it can be represented as a = -k(1) (nu - nu(o)), where nu(o) = 400 km s(-1), i.e., most of CMEs faster than 4...更多
