The Ice Cream Cone Model for Inversing Geometrical Properties of Halo Coronal Mass Ejections
It is suggested recently that most of halo coronal mass ejections (CMEs) may be formed by an ice cream cone-like shell of dense CME electrons. We improve our cone model (Zhao, Plunkett and Liu, 2002) to include the contribution of the top surface of the ice cream part as well as the cone part to the shape of the halo CMEs. It is found that for an ice cream cone with a half sphere sitting on the...
متن کاملInversion solutions of the elliptic cone model for disk frontside full halo coronal mass ejections
[1] A new algorithm is developed for inverting six unknown elliptic cone model parameters from five observed CME halo parameters. It is shown that the halo parameter a includes the information on the coronal mass ejection (CME) propagation direction denoted by two model parameters. On the basis of the given halo parameter a, two approaches are presented to find out the CME propagation direction...

متن کاملDetermination of geometrical and kinematical properties of halo coronal mass ejections using the cone model
[1] Many broadside coronal mass ejections (CMEs) propagate almost radially beyond the first couple of solar radii, and their angular widths remain nearly constant while propagating through the corona. Assuming that these characteristics hold true for halo CMEs that originate far from solar limbs, some useful geometric and kinematic properties of halo CMEs may be reproduced using a simple geomet...
متن کاملA Model for Solar Coronal Mass Ejections
We propose a new model for the initiation of a solar coronal mass ejection (CME). The model agrees with two properties of CMEs and eruptive Ñares that have proved to be very difficult to explain with previous models : (1) very low-lying magnetic Ðeld lines, down to the photospheric neutral line, can open toward inÐnity during an eruption ; and (2) the eruption is driven solely by magnetic free ...
