Formation and Initiation of Erupting Flux Rope and Embedded Filament Driven by Photospheric Converging Motion

In this paper, we study how a flux rope (FR) is formed and evolves into the corresponding structure of a coronal mass ejection (CME) numerically driven by photospheric converging motion. A two-and-a-half-dimensional magnetohydrodynamics simulation is conducted in a chromosphere-transition-corona set...
