Radial oscillations and tidal Love numbers of dark energy stars
arXiv:2010.09373 · doi:10.1140/epjp/s13360-020-00867-x
Abstract
We investigate the properties of relativistic stars made of dark energy. We model stellar structure assuming i) isotropic perfect fluid and ii) 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.
