论文摘要
我们分析了一系列太阳井喷式爆发耀斑产生的三种同源宽冠质量弹出（CME）的形成机制，其强度不断增加（M2.0，M2.6和X1.0）。耀斑起源于2014年3月28日至29日的活动区域12017，间隔约为24小时。基于非线性磁场外推的冠状磁场建模有助于识别封闭磁通绳的耀斑区域内的低覆盖闭合环。我们在所有事件的封闭双极场下获得了双通量绳系统。通量绳的顺序喷发导致同源耀斑，每个耀斑随后是CME。由爆发形成的三个CME中的每一个在从紧凑的喷发源位点扩展后，逐渐达到一个大角度宽度。我们发现这些爆发和CME与“磁性弓形”场景一致：每次紧凑型爆破爆发都坐在一个遥远的磁拱的一英尺中，爆炸了拱门的封闭腿，并吹出拱门以制造宽CME。
We analyze the formation mechanism of three homologous broad coronal mass ejections (CMEs) resulting from a series of solar blowout-eruption flares with successively increasing intensities (M2.0, M2.6, and X1.0). The flares originated from active region NOAA 12017 during 2014 March 28-29 within an interval of approximately 24 hr. Coronal magnetic field modeling based on nonlinear-force-free-field extrapolation helps to identify low-lying closed bipolar loops within the flaring region enclosing magnetic flux ropes. We obtain a double flux rope system under closed bipolar fields for the all the events. The sequential eruption of the flux ropes led to homologous flares, each followed by a CME. Each of the three CMEs formed from the eruptions gradually attain a large angular width, after expanding from the compact eruption-source site. We find these eruptions and CMEs to be consistent with the 'magnetic-arch-blowout' scenario: each compact-flare blowout eruption was seated in one foot of a far-reaching magnetic arch, exploded up the encasing leg of the arch, and blew out the arch to make a broad CME.
