AI 中文总结

该研究旨在通过复合光谱模型在RAVE巡天中搜索双线光谱双星,用三种互补选择找到相关光谱并与自动分类比较,结果吻合良好,还识别出受波长校准问题影响的光谱。

AI 中文摘要

本文利用复合光谱模型对RAVE光谱中的双线光谱双星成分进行研究。通过三种互补选择找到2813条复合光谱,属于2605个独特目标。将结果与基于t-SNE图的自动分类比较,吻合良好。此外还识别出一些受波长校准问题影响的光谱。

英文摘要

I present a study for double-line spectroscopic binaries content in spectra from the RAVE spectra, using composite spectral model. Three complementing selections found 2813 composite spectra, belonging to 2605 unique targets. Also these results were compared with automatic classification based on t-SNE map, which shows good agreement. Additionally I identified several spectra affected by problems with wavelength calibration.
