Quasi-Normal Modes of Stars and Black Holes
- K. Kokkotas, B. Schmidt
- Physics, Medicine
- Living reviews in relativity
- 16 September 1999
AbstractPerturbations of stars and black holes have been one of the main topics of relativistic astrophysics for the last few decades. They are of particular importance today, because of their… Expand
The Einstein Telescope: a third-generation gravitational wave observatory
- M. Punturo, M. Abernathy, +132 authors K. Yamamoto
- Physics
- 7 October 2010
Advanced gravitational wave interferometers, currently under realization, will soon permit the detection of gravitational waves from astronomical sources. To open the era of precision gravitational… Expand
Introducing the CTA concept
- B. Acharya, M. D. Actis, +980 authors P. Żychowski
- Physics
- 2013
The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve the… Expand

Towards gravitational wave asteroseismology
- N. Andersson, K. Kokkotas
- Physics
- 28 November 1997
We present new results for pulsating neutron stars. We have calculated the eigenfrequencies of the modes that one would expect to be the most important gravitational wave sources: the fundamental… Expand
THE R-MODE INSTABILITY IN ROTATING NEUTRON STARS
- N. Andersson, K. Kokkotas
- Physics
- 27 October 2000
In this review we summarize the current understanding of the gravitational-wave driven instability associated with the so-called r-modes in rotating neutron stars. We discuss the nature of the… Expand
On the quasi‐periodic oscillations in magnetars
- A. Colaiuda, H. Beyer, K. Kokkotas
- Physics
- 9 February 2009
We study torsional Alfven oscillations of magnetars, i.e., neutron stars with a strong magnetic field. We consider the poloidal and toroidal components of the magnetic field and a wide range of… Expand
Bayesian timing analysis of giant flare of SGR 180620 by RXTE PCA
- V. Hambaryan, R. Neuhaeuser, K. Kokkotas
- Physics
- 27 December 2010
Aims. By detecting high-frequency quasi-periodic oscillations (QPOs) and estimating their frequencies during the decaying tail of giant flares from soft gamma-ray repeaters (SGRs) useful constraints… Expand
Gravitational Radiation Limit on the Spin of Young Neutron Stars
- N. Andersson, K. Kokkotas, B. Schutz
- Physics
- 17 May 1998
A newly discovered instability in rotating neutron stars, driven by gravitational radiation reaction acting on the stars' r-modes, is shown here to set an upper limit on the spin rate of young… Expand
Gravitational waves from pulsating stars: Evolving the perturbation equations for a relativistic star
- G. Allen, N. Andersson, K. Kokkotas, B. Schutz
- Physics
- 8 April 1997
We consider the perturbations of a relativistic star as an initial-value problem. Having discussed the formulation of the problem ~the perturbation equations and the appropriate boundary conditions… Expand
