Radial oscillations and tidal Love numbers of dark energy stars

Panotopoulos, Grigorios; Rincon, Angel; Lopes, Ilidio

Abstract

We investigate the properties of relativistic stars made of dark energy. We model stellar structure assuming (1) isotropic perfect fluid and (2) a dark energy inspired equation of state, the generalized equation of state of Chaplygin gas, as we will be calling it. The mass-to-radius profiles, the tidal Love numbers as well as the ten lowest radial oscillation modes are computed. Causality, stability and energy conditions are also discussed.
