An astronomer's dozen : spectroscopy of six double-lined binaries and constraints on detection limits.
Abstract
Seven double-lined binaries have been discerned in a group of 11 previously known binaries with f(m) of less than 0.1 solar masses observed at red wavelengths. On the basis of the detection circumstances of the secondaries in these 11 main-sequence systems, it is estimated that secondaries with mass ratios as small as 0.6 can be detected at red wavelengths with solid-state detectors. The secondary appears to be detectable with an approximately solar-type main-sequence system, if its mass function is greater than 0.05 solar masses.
