Gravitational Collapse for the K-essence Emergent Vaidya Spacetime

Abstract

In this paper, we study the gravitational collapse in the {\bf k-}essence emergent gravity using a generalized Vaidya-type metric as a background. We also analyze the cosmic censorship hypothesis for this system. We show that the emergent gravity metric resembles closely to the new type of the generalized Vaidya metrics for null fluid collapse with the {\bf k-}essence emergent mass function, where we consider the {\bf k-}essence scalar field being a function solely of the advanced or the retarded time. This new type of {\bf k-}essence emergent Vaidya metric has satisfied the required energy conditions. The existence of the locally naked central singularity, the strength and the strongness of the singularities for the {\bf k-}essence emergent Vaidya metric are the interesting outcomes of the present work.
