A space X is star-Hurewicz if for each sequence (U_n:n∈N) of open covers of X there exists a sequence (V_n:n∈N) such that for each n, V_n is a finite subset of U_n, and for each x∈X, x∈St(⋃V_n,Un) for all but finitely many n. We investigate the relationship between star-Hurewicz spaces and related spaces, and also study topological properties of star-Hurewicz spaces.
