The Solar Interface Region

我们的目标是研究太阳光球和日冕之间的界面区域。这个界面区由色球和过渡区组成，将太阳光球(温度约6000K)和日冕(温度数百万K)分开。等离子体加热和从光球到日冕的物质供应都发生在这个界面区域，这一点还不是很好理解，也很难研究。小型探测器任务IRIS(界面区成像光谱仪)，发射27。2013年6月)致力于观察这一区域。作为这次成像任务的补充，我们将从气球搭载的日出任务(2013年6月12日发射)获得光球磁场矢量的高分辨率测量。对这两次飞行任务(以及SDO和Hinode)的数据集进行分析，再加上我们小组开发的先进磁场外推和等离子体模拟技术，使我们有独特的机会研究太阳大气的质量和能量供应。

Our aim is to study the interface region between the solar photosphere and solar corona. This interface region, which consists of the chromosphere and transition region, separates the solar photosphere (temperature about 6000 K) and the corona (temperature millions K). Plasma heating and mass supply from the photosphere to the corona take place in this interface region, which is not well understand and difficult to investigate. The small explorer mission IRIS (Interface Region Imaging spectrograph, launched 27. june 2013) is dedicated to observe this region. Complimentary to this imaging mission we will get high resolution measurements of the photospheric magnetic field vector from the balloon borne mission SUNRISE (launched 12. June 2013). An analysis of data sets from these two missions (and additional from SDO and Hinode) together with advanced magnetic field extrapolation and plasma modelling techniques developed in our group give us the unique opportunity to investigate the mass and energy supply of the solar atmosphere.
