Mining unusual and rare stellar spectra from large spectroscopic survey data sets using the outlier-detection method
Monthly Notices of the Royal Astronomical Society(2013)
摘要
The large number of spectra obtained from sky surveys such as the Sloan Digital Sky Survey (SDSS) and the survey executed by the Large sky Area Multi-Object fibre Spectroscopic Telescope (LAMOST, also called GuoShouJing Telescope) provide us with opportunities to search for peculiar or even unknown types of spectra. In response to the limitations of existing methods, a novel outlier-mining method,...
