Comparison between the asteroseismic estimates and dynamical measurements of the mean density and surface gravity. Left panel: ratio of the seismic mean density, , divided by the dynamical mean density, , as a function of the dynamical mean density. Right panel: ratio of the seismic surface gravity, gseis, divided by the dynamical surface gravity, gdyn, as a function of the dynamical surface gravity. Each dot corresponds to an SB2 EB with an oscillating RG component. The blue dots represent those published by Gaulme et al. (2016a), the black dot, the star discovered by Themeßl et al. (2018) and the red dots, those published in this paper, to which we added KIC 4663623, the star from Gaulme et al. (2016a) that we reanalyzed in this study. The correspondence between the letters and the KIC indices are given in Tables 1 and B.1. KIC 7293054 is not shown in this figure because its radius could not be determined dynamically. The seismic estimates for the points shown were obtained with the correction described in Sect. 4.2. The dotted gray and black lines represent the means obtained with the reference values of Mosser et al. (2013) and Themeßl et al. (2018), respectively. The black plain line indicates a ratio of 1.
