Is there an aproximation to know the shape of a dust cloud,etc based on the magnitude/flux curves of stars they transit? Example, can I know if the shape is (at least in 2 dimensions) elliptical, round or just irregular? If somehow the difference in magnitude does not come from the star itself, how can I know the shape of perhaps something that is passing by?
