【摘要】 初态日冕和驱动机制在日冕物质抛射的形成和演化过程中所起的作用是一个引起争论的问题.本文从MHD方程组出发,在不同的初态日冕中,数值模拟了日冕底部新磁通量喷发和热压力扰动两种驱动机制的日冕响应.结果表明,初态日冕和驱动机制对日冕物质抛射的形成及演化都有重要影响.更多还原

【Abstract】 The role of the preevent corona and the driving mechanism in the formation and evolution of CMEs is a disputable problem. In different initial corona, this paper simulates the coronal response to new magnetic flux eruption and thermal energy release at the coronal base. We show that both the preevent corona and the driving mechanism are important in the formation and evolution of CMEs.更多还原
