We have attempted to establish observational evidence for the presence of distant companions that may have acquired and/or absorbed angular momentum during the evolution of multiple systems, thus facilitating or enabling the formation of contact binaries. In this preliminary investigation we use several techniques (some of them distance-independent) and mostly disregard the detection biases of individual techniques in an attempt to establish a lower limit to the frequency of triple systems. While the whole sample of 151 contact binary stars brighter than Vmax = 10 mag gives a firm lower limit of 42% ± 5%, the corresponding number for the much better observed northern-sky subsample is 59% ± 8%. These estimates indicate that most contact binary stars exist in multiple systems.

• ON THE TRIPLE ORIGIN OF BLUE STRAGGLERS (2009, background): “Several observational studies verified that close binaries very often have tertiary components (Tokovinin 2004; Pribulla & Rucinski 2006; D’Angelo et al. 2006; Rucinski et al. 2007), showing a strong dependence between the binary period and the existence of a third companion (Tokovinin et al. 2006).”

• Observational Evidence for Tidal Interaction in Close Binary Systems (2007, background): “Other studies (Isobe et al. 1992; Tokovinin & Smekhov 2002; Pribulla & Rucinski 2006; D’Angelo et al. 2006) also indicated a high frequency of triple systems.”
• RESONANT POST-NEWTONIAN ECCENTRICITY EXCITATION IN HIERARCHICAL THREE-BODY SYSTEMS (2012, background): “Moreover, Pribulla & Rucinski (2006) have surveyed a sample of contact binaries, and noted that 42±5% of 151 of them brighter than 10 mag. are at least triples.”
