New class of naked singularities and their observational signatures

Understand

By imposing suitable junction conditions on a space-like hyper-surface, 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.
