论文摘要
我们报告了沿太阳能天文台（SDO），界面区域成像光谱（IRIS）和1米新真空太阳能望远镜（NVST）沿冠状环（SDO）播种的太阳能射流传播的观察结果。射流的喷射由多热成分组成，并以大于100 km/s的速度传播。在Halpha图像中具有紧凑和圆形的冠状环的偏远脚尖中发现了亮度。大气成像组件（AIA）94ÅPassband在射流底座中落后60 s的远程亮峰的发射峰。据信，远程脚步中的亮度是由非热电子，MHD波和/或传导阵线加热的后果，由射流的磁重新连接过程产生。远程脚步的加热导致沿环的亮光向喷射底座延伸，据信这是色球蒸发。这显然是在弹射器上的制动器，导致在1.5至3 km s $^{ - 2} $的范围内减速，错误为$ \ sim1.0 $ \，km s $ s $ s $^{ - 2} $当发色层蒸发和弹药在Loop顶点附近的位置相遇时。该喷气机的动力学为诊断从远程脚步诊断色球蒸发的独特机会，从中我们推断出330--880 km/s的速度。
We report on observations of a solar jet propagating along coronal loops taken by the Solar Dynamics Observatory (SDO), the Interface Region Imaging Spectragraph (IRIS) and 1-m New Vacuum Solar Telescope (NVST). The ejecta of the jet consist of multi-thermal components and propagate with a speed greater than 100 km/s. Brightenings are found in the remote footpoints of the coronal loops having compact and round-shape in the Halpha images. The emission peak of the remote brightening in the Atmospheric Imaging Assembly (AIA) 94 Åpassband lags 60 s behind that in the jet base. The brightenings in the remote footpoints are believed to be consequences of heating by nonthermal electrons, MHD waves and/or conduction front generated by the magnetic reconnection processes of the jet. The heating in the remote footpoints leads to extension of the brightening along the loops toward the jet base, which is believed to be the chromospheric evaporation. This apparently acts as a brake on the ejecta, leading to a deceleration in the range from 1.5 to 3 km s$^{-2}$ with an error of $\sim1.0$\,km s$^{-2}$ when the chromospheric evaporation and the ejecta meet at locations near the loop apexes. The dynamics of this jet allows a unique opportunity to diagnose the chromospheric evaporation from the remote footpoints, from which we deduce a velocity in the range of 330--880 km/s.
