Asymptotic zero distribution conjecture for Gonchar polynomials of the third kind

Let $\Gamma$ be the set consisting of the boundary of the union of the two unit disks centered at $-1$ and $0$, together with the line segment connecting their intersection points. Let $\operatorname{G_3}(d,q^\prime;z)$ denote the Gonchar polynomial of the third kind in dimension $d$ with conical charge $q^\prime$. Asymptotic zero distribution conjecture. As $d\to\infty$, all zeros of $\operatorname{G_3}(d,q^\prime;z)$ tend to $\Gamma$, and every point of $\Gamma$ attracts zeros of these polynomials. This conjectural description identifies the limiting zero set for the Gonchar polynomials of the third kind; the supplied text does not indicate whether it has been proved or remains open.
