耀斑产生区和休眠活动区的三维速度流

3D Velocity Flows in Flare Productive and Dormant Active Regions

R. A. Maurya, A. Ambastha

摘要:

在第23太阳活动周期间,一些活动区(AR)产生了极高能量的耀斑和日冕物质抛射。与休眠AR和安静区(QR)相比,这些AR预计在特征上是不同的。确定人工反应堆的内部结构和动态是否与其燃烧/日冕物质抛射活动水平有关,将是一个有趣的问题。为了这项调查,我们已经获得了次表面的速度流在几个AR和QR使用环图技术,然后推导出相应的涡度矢量和动力螺旋度密度。

英文摘要:

During Solar Cycle 23, some active regions(ARs) produced extremely energetic flares and CMEs. These ARs are expected to be characteristically distinct as compared to dormant ARs and quiet regions (QRs). It would be interesting to identify whether the internal structure and dynamics of the ARs is related to their flaring/CME activity levels. For this investigation, we have obtained sub-surface velocity flows in several ARs and QRs using the ring diagram technique, and then derived the corresponding vorticity vector and kinetic helicity density.
