| 摘要 | In this paper we detect double-lined spectroscopic binaries (SB2) in five open clusters: NGC 2243, NGC 2420, NGC 3532, NGC 6253, and NGC 6705 (M 11) using a method based on high values of the projected rotational velocity when they are fitted with single star spectral model. Observed spectra were obtained from the European Southern Observatory archive. The method was validated on the sets of synthetic spectra for the single and binary stars. It is able to reliably select spectroscopic binaries without confusing them with single stars, if the components in a binary rotate slowly and the radial velocity separation is sufficiently high. We found 60 SB2 candidates: two in NGC 2243, eight each in NGC 2420 and NGC 3532, 17 in NGC 6253, and 25 in NGC 6705. Comparison with literature confirms 18 of them, thus we found 42 new SB2 candidates. |
