TL;DR
This paper characterizes when the toric varieties derived from graph cubeahedra are Fano or weak Fano, based on properties of the underlying finite simple graph.
Contribution
It provides a complete combinatorial criterion linking graph properties to the Fano and weak Fano conditions of associated toric varieties.

Abstract
We give a necessary and sufficient condition for the nonsingular projective toric variety associated to the graph cubeahedron of a finite simple graph to be Fano or weak Fano in terms of the graph.
