Abstract
AbstractIn this work we investigate the properties of compact stars in the Randall‐Sundrum type II brane‐world model. We analyze the properties of quark and hadronic stars using the MIT bag model and a relativistic mean‐field model for the equation of state. We show that the causality limit in brane‐world models coincides with the Schwarzschild limit. Hence, there is a region in the mass‐radius plane that is forbidden in General Relativity for causal equations of state but can be accessed within brane‐world models. We also show that stable compact stars of arbitrarily large mass are possible because they can be supported against collapse by the non‐local bulk effects on the brane. This features provide a potential test for the existence of extra dimensions through the observation of neutron star's masses and radii. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
