In System KIC 9246715, How Far Does One Star Orbit the Other?
The AAS Nova article cites Rawls et al. 2016,
who analyze light curves and spectra of the eclipsing binary KIC 9246715 to estimate its physical properties.
Besides the stellar masses and radii in the article, their Table 2 lists orbital semimajor axis a = 211 R&#9737; = 147 million km = 0.98 au, and orbital eccentricity e = 0.356.
During the 171-day period, the distance between the two stars varies between 95 and 199 million km, or 0.63 and 1.33 au.
