摘要:

在这项研究中,我们提出了11个经常性的太阳喷流起源于两个不同的网站(网站1和网站2)彼此接近(~ 11毫米)在NOAA活动区(AR)12035在2014年4月15日至16日的调查。喷流是由太阳动力学观测卫星(SDO)上的大气成像组件(AIA)望远镜观测到的。印度奈尼塔尔的Aryabhatta观测科学研究所用H-alpha望远镜观测到两个喷流。4月15日通量出现是重要的网站1,而在4月16日通量出现和取消机制参与在这两个网站。两个地点的喷流有平行的轨迹,并以100至360公里/秒的速度向南移动。我们观察到这两个网站之间的一些连接与一些转移的增亮。地点2的射流发生在第二天,并有向地点1的射流移动并与它们合并的趋势。我们推测,滑移的射流可以解释的复杂的拓扑结构的区域存在一些低海拔的零点和许多准分界线层(QSL),可以相互交叉。

英文摘要:

In this study, we present the investigation of eleven recurring solar jets originated from two different sites (site 1 and site 2) close to each other (~ 11 Mm) in the NOAA active region (AR) 12035 during 15--16 April 2014. The jets were observed by the Atmospheric Imaging Assembly (AIA) telescope onboard the Solar Dynamics Observatory (SDO) satellite. Two jets were observed by the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, India telescope in H-alpha. On 15 April flux emergence is important in site 1 while on 16 April flux emergence and cancellation mechanisms are involved in both sites. The jets of both sites have parallel trajectories and move to the south with a speed between 100 and 360 km/s. We observed some connection between the two sites with some transfer of brightening. The jets of site 2 occurred during the second day and have a tendency to move towards the jets of site 1 and merge with them. We conjecture that the slippage of the jets could be explained by the complex topology of the region with the presence of a few low-altitude null points and many quasi-separatrix layers (QSLs), which could intersect with one another.
