Special point on the mass radius diagram of hybrid stars

Abstract

An analytical study that explains the existence of a very small region on the mass radius diagram of hybrid stars where all of the lines representing the sequences of models with different constant values of the bag constant B intersect is presented. This circumstance is shown to be a consequence of the linear dependence of pressure on energy density in the quark cores of hybrid stars.
