论文摘要
1250埃埃斯特罗姆之间的光谱区域 - 3000埃包含重要的光谱线，以了解行星的形态结构和演变 星云。这是紫外线通过连续和发射线中的各种滤波器带（例如C IV，He I，Mg II等）采样的区域。我们已经绘制了几个具有不同特征的行星星云，形态学的范围从躁郁症到宽且分散，并且在各种电离状态下，将紫外线与X射线形态进行比较，无论X射线图像也可用。紫外线的主要意外发现是检测到某些行星星云周围未发现的，冷，荧光，分子氢气的检测。这可能是解决缺失质量问题的可能解决方案。在这里，我们对迄今为止的研究进行了评论（无论是出版还是出版）。
The spectral region between 1250 Angstroms - 3000 Angstroms contains important spectral lines to understand the morphological structures and evolution of planetary nebulae. This is the region sampled by UVIT through various filter bands both in the continuum and in emission lines (e.g. C IV, He I, Mg II etc.). We have mapped several planetary nebulae with different characteristics, ranging in morphology from bipolar to wide and diffuse, and in various states of ionization, comparing the UV with the x-ray morphologies wherever the x-ray images were also available. The major unanticipated discovery with UVIT has been the detection of previously undetected, cold, fluorescent, molecular hydrogen gas surrounding some planetary nebulae. This may be a possible solution to the missing mass problem. Here we present a review of our studies so far done (both published and on going) with UVIT.
