Abstract:
In this talk I review some general ideas of black holes in classical GR, and also some of their paradoxes. Then, I discuss a proposal based on the Schwarzschild’s interior solution with constant density (Schwarzschild star, for short), which allows the compactness to approach arbitrarly close to the Schwarzschild radius. It turns out that in this limiting case, this configuration becomes essentially a ‘gravastar-like’ object. I review briefly some of my recent research, which seems to indicate that this object could be a good black hole mimicker
