Spectroscopic triples and a chance alignment: a solution for the problem of suspicious mass ratios for SB2s from Wilson method.
KOVALEV M., CHEN X. and HAN Z.
Abstract (from CDS):
We selected three double-lined spectroscopic binary systems which have extreme mass ratios, if measured using the Wilson method. We analysed medium resolution spectroscopic observations and space-based photometry and find that all these systems are not SB2, but rather triple systems and a chance alignment of another star with SB1 that have an unseen component. Therefore, suspicious mass ratios determined by the Wilson method for some double-lined spectroscopic binary systems aren't correct as these systems are more complex.
