Sets expressible as finite unions of starshaped sets

Several papers have appeared with descriptions of sets that are expressible as unions of 2 or 3 starshaped sets. The general problem is relevant since it is closely related to the classical "Art Gallery Problem". Some new solutions, for generic values of the parameters, are presented here....
