This Letter reports observations of an event that connects all major classes of solar eruptions: those that erupt fully into the heliosphere versus those that fail and are confined to the Sun, and those that eject new flux into the heliosphere, in the form of a flux rope, versus those that eject only new plasma in the form of a jet. The event originated in a filament channel overlying a circular polarity inversion line and occurred on 2016 March 13 during the extended decay phase of the active region designated NOAA 12488/12501. The event was especially well observed by multiple spacecraft and exhibited the well-studied null-point topology. We analyze all aspects of the eruption using Solar Dynamics Observatory Atmospheric Imaging Assembly and Helioseismic and Magnetic Imager, Solar-Terrestrial Relations Observatory Extreme Ultraviolet Imager, and Solar and Heliospheric Observatory Large Angle and Spectrometric Coronagraph (SOHO LASCO) imagery. One section of the filament undergoes a classic failed eruption with cool plasma subsequently draining onto the section that did not erupt, but a complex structured coronal mass ejection/jet is clearly observed by SOHO/LASCO C2 shortly after the failed filament eruption. We describe in detail the slow buildup to eruption, the lack of an obvious trigger, and the immediate reappearance of the filament after the event. The unique mixture of major eruption properties observed during this event places severe constraints on the structure of the filament channel field and, consequently, on the possible eruption mechanism.

对“罗塞塔石碑”太阳爆发的观测研究

这封信报告了一个事件的观察结果,该事件将所有主要类型的太阳爆发联系起来:完全爆发到日光层的那些与那些失败并被限制在太阳内的那些,以及那些以通量的形式将新通量喷射到日光层的那些绳索,与那些仅以射流形式喷射新等离子体的绳索相比。该事件起源于一个覆盖圆极性反转线的灯丝通道,发生在 2016 年 3 月 13 日,在指定为 NOAA 12488/12501 的活动区的扩展衰减阶段期间。该事件被多个航天器特别好地观察到,并展示了经过充分研究的零点拓扑。我们使用太阳动力学天文台大气成像组件和日震和磁成像仪、日地关系天文台极紫外成像仪、太阳和日光层天文台大角度和光谱日冕仪 (SOHO LASCO) 图像。灯丝的一部分经历了典型的失败喷发,随后冷等离子体流向未喷发的部分,但在灯丝喷发失败后不久,SOHO/LASCO C2 清楚地观察到了结构复杂的日冕物质喷射/射流。我们详细描述了喷发的缓慢积累、缺乏明显的触发因素以及事件发生后灯丝的立即重新出现。在此事件中观察到的主要喷发特性的独特混合对细丝通道场的结构以及可能的喷发机制产生了严重的限制。灯丝的一部分经历了典型的失败喷发,随后冷等离子体流向未喷发的部分,但在灯丝喷发失败后不久,SOHO/LASCO C2 清楚地观察到了结构复杂的日冕物质喷射/射流。我们详细描述了喷发的缓慢积累、缺乏明显的触发因素以及事件发生后灯丝的立即重新出现。在此事件中观察到的主要喷发特性的独特混合对细丝通道场的结构以及可能的喷发机制产生了严重的限制。灯丝的一部分经历了典型的失败喷发,随后冷等离子体流向未喷发的部分,但在灯丝喷发失败后不久,SOHO/LASCO C2 清楚地观察到了结构复杂的日冕物质喷射/射流。我们详细描述了喷发的缓慢积累、缺乏明显的触发因素以及事件发生后灯丝的立即重新出现。在此事件中观察到的主要喷发特性的独特混合对细丝通道场的结构以及可能的喷发机制产生了严重的限制。我们详细描述了喷发的缓慢积累、缺乏明显的触发因素以及事件发生后灯丝的立即重新出现。在此事件中观察到的主要喷发特性的独特混合对细丝通道场的结构以及可能的喷发机制产生了严重的限制。我们详细描述了喷发的缓慢积累、缺乏明显的触发因素以及事件发生后灯丝的立即重新出现。在此事件中观察到的主要喷发特性的独特混合对细丝通道场的结构以及可能的喷发机制产生了严重的限制。
