摘要：
In this work, we count (classes of) central configurations of the restricted (5 + 1) and (4 + 1)-body problems whose primaries form either a centered square or a centered equilateral triangle. More precisely, we count the central configurations formed by the centered polygons and a body of zero mass as the value of the mass of the central body varies. For this purpose, we study the bifurcation set. In addition, we classify the bifurcations as saddle-node bifurcations.
