Description
Within the context of general relativity, black holes must contain a singular core. It is widely believed that singularities are not truly a physical feature, but rather a sign indicating the breakdown of the general relativistic description. Among the possible non-singular scenarios, regular black holes and or horizonless ultracompact stars have taken a particular preeminence. In this talk, I am going to discuss generic instability mechanisms that must be addressed to make these objects viable models of non-singular spacetimes.
