  • Geometrical Implication of the CME Earthward Direction

    1/4/2009· In this study, we present the geometrical implication of this parameter by comparing with the parameters from a CME cone model. Major results from this study can be summarized as follows. First, we derive an analytic relationship between the cone model parameters (the half angular width of a cone and the angle between the cone axis and the plane of sky) and the earthward direction parameter.

  • An ice‐cream cone model for coronal mass ejections Xue

    Assuming that a CME is isotropic and is emitted from a point, one can image that the front edge of the CME should form a sphere‐like shape. Thus we consider that (1) the shape of CMEs is a symmetrical ice‐cream cone, combining a cone with a sphere.

  • An ice‐cream cone model for coronal mass ejections

    [16] In our model, the criteria between a disk‐center‐covered CME and a non‐disk‐center‐covered CME is whether the projected angular width (PAW) of the ice‐cream cone on the sky plane is greater than 180 or not.The relationship of cos = sin θ 0 cos ϕ 0 specifies the boundary between this two types of CME in the ice‐cream cone model.

    [15] Note that if a = b and h = 0, then we have cos θ = 0.In this case the solution is degenerate since the solution for angular width ω is not unique. This occurs when the orientation of the cone CME is aligned with the line‐of‐sight. This case is consistent with Zhao et al.'s [2002] study. study.
