Title: Neutron Star Structure in Hořava-Lifshitz Gravity
Speaker: Edwin J. Son (NIMS)
Abstract: We present interesting aspects of a modified theory of gravity called Hořava-Lifshitz (HL) gravity that can be constrained by the phenomenological and observational prospects in terms of neutron star (NS) structure and equation-of-state models. The deformation in HL gravity from general relativity (GR) can change typical features of the NS structure. In this Letter, we investigate the NS structure by deriving Tolman-Oppenheimer-Volkoff equation in HL gravity. We find that a NS in HL gravity with larger radius and heavier mass than a NS in GR remains stable without collapsing into a black hole.
