Orbital configurations of the systems. Top: orbital period vs. relative radii for the 35 systems from Gaulme et al. (2014) and this paper. The size of each symbol represents the amplitude of stellar variability and the gray scale indicates the pulsation mode amplitude (white – no modes; black – large amp.) Bottom: same but for the eccentricity of the binary system. This figure is an updated version of Fig. 6 from Gaulme et al. (2014).
