Celestia representation for the binary star+planet in
Ortiz et al. (arXiv:1608.00963 [astro-ph.EP]). Note this planet is supplied in extrasolar.ssc for a single star representation, so the relevant sections must be commented out of that file first otherwise you'll end up with one version of the planet orbiting the barycentre, the other orbiting the primary star.
The secondary could be a main sequence star or a white dwarf, here I've gone with the main sequence star version. I've used the orbital inclination and ascending node given in the figure 8. I estimated the stellar properties for star B using
isochrones and the radius of the planet is estimated using
forecaster.
