| Abstract: | . The equations governing static stellar models in Newtonian gravity are equivalent to a Lane-Emden type equation. For such equations existence,uniqueness,and regularity of global solutions is shown for a large class of right-hand sides, including a subclass of non-Lipschitz continuous equations of state which is relevant if e.g. phase transitions occur. Furthermore, it is shown that for a star of finite radius the polytropic index of the equation of state is not necessarily bounded near the star's surface. |
