We discuss the construction of perfect fluid stellar objects having optical
geometries with multiple necks corresponding to spatially closed unstable
lightlike geodesics. We prove that physically reasonable equations of state
can give rise to stellar equilibria with arbitrarily many necks. We also s
how how a first-order phase transition can give rise to quite pronounced se
condary necks. The analysis is carried out using a modification of a recent
dynamical systems formulation of the TOV equations due to Nilsson and Uggl
a. Our reformulation allows for a very general family of equations of state
including, for example, phase transitions.
