摘要:

我们使用协调的日出SOT/EIS观测,包括高分辨率磁图,色球和TR成像和TR/日冕光谱在第一次测试中,研究如何驱动的TR的动态的高度动态的光球磁场和无处不在的色球波。初步分析表明,这些联系是相当微妙的,需要结合技术,包括磁场外推,频率过滤的时间序列和比较合成色球和TR图像从先进的三维数值模拟。作为第一个结果,我们发现的磁通量出现的签名,以及3和5兆赫波功率以上的地区增强光球磁场在色球,过渡区和日冕发射。

英文摘要:

We use coordinated Hinode SOT/EIS observations that include high-resolution magnetograms, chromospheric and TR imaging and TR/coronal spectra in a first test to study how the dynamics of the TR are driven by the highly dynamic photospheric magnetic fields and the ubiquitous chromospheric waves. Initial analysis shows that these connections are quite subtle and require a combination of techniques including magnetic field extrapolations, frequency-filtered time-series and comparisons with synthetic chromospheric and TR images from advanced 3D numerical simulations. As a first result, we find signatures of magnetic flux emergence as well as 3 and 5 mHz wave power above regions of enhanced photospheric magnetic field in both chromospheric, transition region and coronal emission.
