New class of naked singularities and their observational signatures

By imposing suitable junction conditions on a spacelike hypersurface, we obtain a two-parameter family of possible static configurations from gravitational collapse. These exemplify a new class of naked singularities. We show that these admit a consistent description via a two-fluid model, one of which might be dust. We then study lensing and accretion disk properties of our solution and point out possible differences with black hole scenarios. The distinctive features of our solution compared to the existing naked singularity solutions in the literature are discussed.
