对太阳耀斑的遥振荡响应

Remote Oscillatory responses to a solar flare

Aleksandra Andic, R. T. James McAteer

摘要:

控制太阳能量储存和释放的过程都与太阳磁场有关。我们证明了在太阳低层大气中,耀斑释放的能量和振荡功率增加之间存在磁联系。在活跃区域的振荡功率往往会增加,在不同的位置,但不是在该地区本身的爆炸事件的反应。我们进行定时研究,并表明,这可能是由一个大规模的区域之间的磁连接,而不是全球传播的波。我们表明,振荡往往存在于较长的寿命波列在短周期(P<200秒)的耀斑的时间。这可能是耀斑能量在整个太阳大气中重新分布的一种机制。

英文摘要:

The processes governing energy storage and release in the Sun are both related to the solar magnetic field. We demonstrate the existence of a magnetic connection between energy released caused by a flare and increased oscillatory power in the lower solar atmosphere. The oscillatory power in active regions tends to increase in response to explosive events at a different location, but not in the region itself. We carry out timing studies and show that this is probably caused by a large scale magnetic connection between the regions, and not a globally propagating wave. We show that oscillations tend to exist in longer lived wave trains at short periods (P< 200s) at the time of a flare. This may be a mechanism by which flare energy can be redistributed throughout the solar atmosphere.
