论文摘要
语境。已知太阳活跃区具有喷气机。这些喷气机与加热和颗粒释放到太阳风中有关。 目的。我们的目的是了解活动区域内冠状动力喷气机的空间分布，以了解是否存在优先位置。 方法。我们在2-3.5天的时间内使用太阳能动力学观测器大气成像组装数据分析了五个活动区域，当时活动区域靠近磁盘中心。每个活动区域的年龄，磁场强度和拓扑都不同。我们开发了一种确定喷气机的位置和长度的方法。 结果。在活跃区域的边缘观察到喷气机的频率更高，并且位于强烈的前阳场周围更密集。我们活跃区域的冠状喷射次数取决于活动区域的年龄。较旧的活跃地区比年轻的喷气机多。在活跃区域的边缘上显着观察到喷气机，而在中心则不经常观察到。喷气机的数量与整个活动区域中的平均未签名磁场和总磁通密度无关。喷气式飞机位于坚固的领先黑子的边缘。
Context. Solar active regions are known to have jets. These jets are associated with heating and the release of particles into the solar wind. Aim. Our aim is to understand the spatial distribution of coronal jets within active regions to understand if there is a preferential location for them to occur. Methods. We analysed five active regions using Solar Dynamics Observatory Atmospheric Imaging Assembly data over a period of 2-3.5 days when the active regions were close to disk centre. Each active region had a different age, magnetic field strength, and topology. We developed a methodology for determining the position and length of the jets. Results. Jets are observed more frequently at the edges of the active regions and are more densely located around a strong leading sunspot. The number of coronal jets for our active regions is dependent on the age of the active region. The older active regions produce more jets than younger ones. Jets were observed dominantly at the edges of the active regions, and not as frequently in the centre. The number of jets is independent of the average unsigned magnetic field and total flux density in the whole active region. The jets are located around the edges of the strong leading sunspot.
