Journal ArticleDOI
How to tell a gravastar from a black hole
TL;DR: In this paper, a general class of gravastars were constructed and conditions for their existence as equilibrium solutions of the Einstein equations were determined. But their quasi-normal modes differ from those of a black hole of the same mass.
Journal ArticleDOI
Did GW150914 produce a rotating gravastar
TL;DR: In this article, the authors consider the hypothesis that the merging objects were indeed gravastars and explore whether the merged object could therefore be not a black hole but a rotating gravastar.
Journal ArticleDOI
Ergoregion instability in rotating gravastars
TL;DR: In this article, a detailed analysis on the relevance of the ergoregion instability for the viability of gravastars is presented, and it is shown that not all rotating objects are unstable.
Journal ArticleDOI
Constraining the equation of state of high-density cold matter using nuclear and astronomical measurements
TL;DR: In this paper, the authors present a Bayesian approach to constrain the properties of cold dense matter by using the full posterior probability distributions of measurements rather than imposing a cut on the maximum mass or other quantities.
Journal ArticleDOI
Fundamental oscillation modes of neutron stars: validity of universal relations
TL;DR: In this paper, the authors studied the frequency and damping time of nonrotating neutron stars in general relativity by solving the linearized perturbation equations, with the aim to establish ''universal'' relations that depend only weakly on the equations of state (EOS).
