Comparing models of rapidly rotating relativistic stars constructed by two numerical methods

- N. Stergioulas, J. Friedman
- Physics
- 8 November 1994

We present the first direct comparison of codes based on two different numerical methods for constructing rapidly rotating relativistic stars. A code based on the Komatsu-Eriguchi-Hachisu (KEH)… Expand

Neutron-star radius constraints from GW170817 and future detections

- A. Bauswein, O. Just, H. Janka, N. Stergioulas
- Physics
- 18 October 2017

We introduce a new, powerful method to constrain properties of neutron stars (NSs). We show that the total mass of GW170817 provides a reliable constraint on the stellar radius if the merger did not… Expand

Rotating Relativistic Stars

- J. Friedman, N. Stergioulas
- Physics
- 11 February 2013

The masses of neutron stars are limited by an instability to gravitational collapse and an instability driven by gravitational waves limits their spin. Their oscillations are relevant to x-ray… Expand

Approximate matching of analytic and numerical solutions for rapidly rotating neutron stars

- E. Berti, N. Stergioulas
- Physics
- 13 October 2003

We investigate the properties of a closed-form analytic solution recently found by Manko et al. for the exterior space-time of rapidly rotating neutron stars. For selected equations of state we… Expand

Three-dimensional relativistic simulations of rotating neutron-star collapse to a Kerr black hole

- L. Baiotti, I. Hawke,
+5 authors E. Seidel - Physics
- 6 March 2004

We present a new three-dimensional fully general-relativistic hydrodynamics code using high-resolution shock-capturing techniques and a conformal traceless formulation of the Einstein equations.… Expand

Prospects for fundamental physics with LISA

- E. Barausse, E. Berti,
+318 authors M. Zumalacárregui - Physics, Education
- 27 January 2020

In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental physics. Given the… Expand

Towards a stable numerical evolution of strongly gravitating systems in general relativity: The conformal treatments

- M. Alcubierre, B. Bruegmann,
+5 authors R. Takahashi - Physics
- 17 March 2000

We study the stability of three-dimensional numerical evolutions of the Einstein equations, comparing the standard ADM formulation to variations on a family of formulations that separate out the… Expand

Nonaxisymmetric Neutral Modes in Rotating Relativistic Stars

- N. Stergioulas, J. Friedman
- Physics
- 21 May 1997

We study nonaxisymmetric perturbations of rotating relativistic stars modeled as perfect-fluid equilibria. Instability to a mode with angular dependence exp (im) sets in when the frequency of the… Expand
