Numerical model of coronal streamer
This paper focuses on a single £uid, two-dimensional, axisymmetric, time-dependent, magnetohydrodynamic numerical simulation of the forma- tion and evolution of a coronal streamer in a current sheet. Two types of evolution are described: (a) the disruption of the streamer in a CME and (b) the dissolution of the streamer probably caused by the current sheet dissipation in the solar atmosphere. In the ¢rst case, the ejected plasmoid density reaches
