Slowly rotating gravastars
Philip Beltracchi, Paolo Gondolo, Emil Mottola
We solve Einstein's equations for slowly-rotating gravitational condensate stars (gravastars) up to second order in the rotation by expanding about the spherically symmetric gravas…

Surface Stress Tensor and Junction Conditions on a Rotating Null Horizon
Philip Beltracchi, Paolo Gondolo, Emil Mottola
The general form of the surface stress tensor of an infinitesimally thin shell located on a rotating null horizon is derived, when different interior and exterior geometries are jo…
