太阳耀斑能量过程的多波长研究

Multi-wavelength Study of Energetic Processes during Solar Flares occurrence

Shirsh Lata Soni, Radhe Shyam Gupta, Adya Prasad Mishra

摘要:

本文试图了解在太阳耀斑期间太阳大气不同层中发生的物理过程。为了全面了解耀斑,我们必须分析多波长数据集,因为不同波长的辐射来自太阳大气的不同层。此外,耀斑是短暂的和局部的事件观察到发生在所有的耀斑。基于这些考虑,我们对两个典型的耀斑事件进行了多波长分析。一个事件发生在靠近太阳圆盘中心的地方,另一个发生在靠近边缘的地方。在前一种情况下,我们研究了来自太阳大气低层的发射。因此,色球、过渡区和光球磁图都可以进行分析。另一方面,在近临事件中,日冕特征可以清楚地研究。本文研究的第一个事件是位于S10E14的活动区NOAA 10649的M1.1级耀斑,第二个事件是位于S12W90的活动区NOAA 10713的M1.4级耀斑。在这两种情况下,我们都观察到了优秀的多波长数据集。多仪器数据的观测清楚地表明,耀斑发生在太阳黑子附近。这些是具有混合极性的强磁场区域。

英文摘要:

This paper is an attempt to understand the physical processes occurring in different layers of solar atmosphere during a solar flare. For a complete understanding of the flare we must analyze multi-wavelength datasets, as emission at different wavelength originates from different layers of the solar atmosphere. Also, flares are transient and localized events observed to occur at all longitudes. With these considerations, we have carried out multi-wavelength analysis of two representative flare events. One event occurred close to the centre of the solar disk and other occurred close to the limb. In the former case, we examine the emission from the lower layers of the solar atmosphere. Therefore the chromospheres, transition region and also the photospheric magneto-gram can be analyzed. On the other hand, in near-limb event, coronal features can be clearly studied. In this paper, the first event studied is the M 1.1 class flare from the active region NOAA 10649 located at S10E14 and the second event is the M 1.4 class flare from the active region NOAA 10713 located at S12W90. In both cases, we have observed the excellent multi-wavelength data sets. The observations from multi-instrumental data clearly shows that flares occur in the vicinity of sunspots. These are regions of strong magnetic field with mixed polarity.
