Search for double-line spectroscopic binaries in RAVE survey

Abstract

I present a study for double-line spectroscopic binaries content in RAVE DR6 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.
