Rotating compact strange stars

- Physics
- 1 July 2000
We compute numerical models of uniformly rotating strange stars (SS) in general relativity for the recently proposed QCD-based equation of state (EOS) of strange quark matter (Dey et al. 1998).…
Jacobi like bar mode instability of relativistic rotating bodies
- D. Gondek-Rosińska, E. Gourgoulhon
- Physics

We perform some numerical studies of the secular triaxial instability of rigidly rotating homogeneous fluid bodies in general relativity. In the Newtonian limit, this instability arises at the…

Population synthesis of double neutron stars

Using the StarTrack binary population synthesis code we model the population of double neutron stars in the Galaxy. We include a detailed treatment of the spin evolution of each pulsar due to…
The eccentricity distribution of compact binaries

The current gravitational wave detectors have reached their operational sensitivity and are nearing detection of compact object binaries. In the coming years, we expect that the Advanced LIGO/VIRGO…
A New View on the Maximum Mass of Differentially Rotating Neutron Stars
- D. Gondek-Rosińska, I. Kowalska, L. Villain, M. Ansorg, M. Kucaba
- Physics
- 8 September 2016
We study the main astrophysical properties of differentially rotating neutron stars described as stationary and axisymmetric configurations of a moderately stiff Γ = 2 polytropic fluid. The high…
Impact of the nuclear equation of state on the last orbits of binary neutron stars

- Physics
- 9 June 2004
We present calculations of quasi-equilibrium sequences of irrotational binary neutron stars based on realistic equations of state (EOS) for the whole neutron star interior. Three realistic nuclear…
Last orbits of binary strange quark stars

- Physics
- 26 November 2004
We present the first relativistic calculations of the final phase of inspiral of a binary system consisting of two stars built predominantely of strange quark matter (strange quark stars). We study…
Are rotating strange quark stars good sources of gravitational waves
- D. Gondek-Rosińska, E. Gourgoulhon, P. Haensel
- Physics, Geology
- 5 November 2003
We study the viscosity driven (Jacobi-like) bar mode instability of rapidly rotating strange stars in general relativity. A triaxial, "bar shaped" compact star could be an efficient source of…
Low-mass quark stars as Maclaurin spheroids
- P. Amsterdamski, T. Bulik, D. Gondek-Rosińska, W. Kluźniak
- Physics, Geology
- 29 December 2000
We show that in the limit of low masses (M<0.1M solar), the orbital and rotational frequencies in exact relativistic numerical models of rotating, axially symmetric, quark stars coincide with those…
