[5.05] Tertiary Companions to MaCHO Eclipsing Binaries

We have looked at 700 stars, flagged as eclipsing binaries by the MaCHO database. Of these stars, only about 10% actually show eclipsing binary light curves. We have examined these data for the presence of a tertiary companion, as indicated by a sinusoidally varying delay in the time of eclipse. Here we present our most promising candidates for tertiary companions.
