“…In multiple systems, the evolutionary scenarios may be even more different and variegated (Toonen et al [31][32][33]). For example, it is hypothesized that a significant fraction of the common envelope binaries (the supposed progenitors of cataclysmic variables), type Ia supernovae (Maoz et al [34]), and contact binaries (of the W UMa type) might be formed through some interactions with a third body (Eggleton [35]; Paczy ński et al [36]; Csizmadia et al [37]); •…”

Close, compact, hierarchical, and multiple stellar systems, i.e., multiples having an outer orbital period from months to a few years, comprise a small but continuously growing group of the triple and multiple star zoo. Many of them consist of at least one eclipsing pair of stars and, therefore, exhibit readily observable short-term dynamical interactions among the components. Thus, their dynamical and astrophysical properties can be explored with high precision. In this paper we present an overview of the history of the search for additional components around eclipsing binaries from the first serendipitous discoveries to more systematic recent studies. We describe the different observational detection methods and discuss their connections to the different kinds of astrophysical and dynamical information that can be mined from different datasets. Moreover, the connection amongst the observable phenomena and the long-term dynamics of such systems is also discussed.

“…Only a very few photometric light curves exist in the literature, such as the recent ground‐based photoelectric observations in B and V bands given by Dumitrescu, Iliev & Tudose (2004). Most of the observations give the times of minima and there are several of these in the literature (Tanriverdi et al 2003; Albayrak et al 2005b; Drozdz & Ogloza 2005; Hübscher, Paschke & Walter 2005, 2006; Porowski 2005; Csizmadia et al 2006; Nelson 2007). Rucinski et al (2001) classified the system as a W UMa‐type contact binary of an A subtype, with a mass ratio of q sp = 0.305 ± 0.005 and an A4V spectral type.…”

We present results of the modelling of multicolour light curves of 10 contact binary systems: V376 And, V523 Cas, CC Com, BX Dra, FG Hya, UZ Leo, XY Leo, AM Leo, EX Leo and RT LMi. The solutions resulted in a contact configuration for all systems. We found only FG Hya and UZ Leo to be in deep contact, the latter almost filling the outer critical lobe. The absolute parameters of the components have been determined with an accuracy of about a few per cent based on combined photometric and radial velocity curves, enlarging the sample of systems to 58 for which the physical parameters have been obtained in a uniform way. All but three systems (BX Dra, AM Leo and RT LMi) show asymmetries and peculiarities in the observed light curves, interpreted as resulting from their magnetic activity.
