标题： Classification of 2.4-45.2 Micron Spectra from the ISO Short Wavelength Spectrometer

摘要： 红外空间观测台使用短波长光谱仪以全光栅扫描模式（2.4-45.2微米）观察了超过900个天体。我们利用这些数据开发了一个全面的光谱分类系统。源根据光谱能量分布（SED）的整体形状被分配到不同的组中。这些组包括裸露恒星、尘埃恒星、温暖尘埃壳层、冷尘埃壳层、非常红的源以及具有发射线但未检测到连续谱的源。这些组进一步根据塑造SED的光谱特征划分为子组，例如硅酸盐或富碳尘埃发射、硅酸盐吸收、冰吸收以及细结构或复合线。讨论了数据和数据处理的注意事项，以及数据库固有的偏差。我们还研究了子组如何与源从主序星到主序星的演化相关，以及此分类方案与先前系统的关联。 显示英文摘要

摘要： The Infrared Space Observatory observed over 900 objects with the Short Wavelength Spectrometer in full-grating-scan mode (2.4-45.2 micron). We have developed a comprehensive system of spectral classification using these data. Sources are assigned to groups based on the overall shape of the spectral energy distribution (SED). The groups include naked stars, dusty stars, warm dust shells, cool dust shells, very red sources, and sources with emission lines but no detected continuum. These groups are further divided into subgroups based on spectral features that shape the SED such as silicate or carbon-rich dust emission, silicate absorption, ice absorption, and fine-structure or recombination lines. Caveats regarding the data and data reduction, and biases intrinsic to the database, are discussed. We also examine how the subgroups relate to the evolution of sources to and from the main sequence and how this classification scheme relates to previous systems.
