Neutron star structure in Hořava-Lifshitz gravity
Kyungmin Kim, J. J. Oh, Chan Park, Edwin J. Son
Abstract
We present interesting aspects of neutron stars (NSs) from the standpoint of a modified theory of gravity called Ho\ifmmode \check{r}\else \v{r}\fi{}ava-Lifshitz (HL) gravity. A deviation from general relativity (GR) in HL gravity can change typical features of the NS structure. In this study, we investigate the NS structure by deriving the Tolman-Oppenheimer-Volkoff equation in HL gravity. We find that a NS in HL gravity with a larger radius and heavier mass than a NS in GR remains stable without collapsing into a black hole.
