Properties of Point Mass Lenses On A Regular Polygon and The Problem of Maximum Number of Images
S. Mao, A. O. Petters, H. J. Witt
We study the critical curves, caustics, and multiple imaging due to one of the simplest many-body gravitational lens configurations: equal-mass point masses on the vertices of a re…
