Radial oscillations and tidal Love numbers of dark energy stars

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 ti...

Zusammenfassung:	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.
