Low-mass quark stars as Maclaurin spheroids
P. Amsterdamski, T. Bulik, D. Gondek-Rosinska +1
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 co…
Relativistic models of kHz QPOs
W. Kluzniak
After reviewing the general-relativistic ``gap'' model of accretion, I discuss its relation to the high frequency quasi-periodic oscillations observed in low-mass X-ray binaries. T…
Innermost stable circular orbits around rotating compact quark stars and QPOs
D. Gondek-Rosinska, T. Bulik, w. Kluzniak +2
It has been suggested that observations of quasi periodic oscillations (QPOs) in the X-ray fluxes from low mass X-ray binaries can be used to constrain the mass of the compact obje…
Population synthesis of neutron stars, strange (quark) stars and black holes
Krzysztof Belczynski, Tomasz Bulik, Wlodzimierz Kluzniak
We compute and present the distribution in mass of single and binary neutron stars, strange stars, and black holes. The calculations were performed using a stellar population synth…
Newtonian hydrodynamics of the coalescence of black holes with neutron stars III: Irrotational binaries with a stiff equation of state
William H. Lee
We present a hydrodynamical study of the final stages of inspiral in a black hole-neutron star (NS) binary. We use a Newtonian 3D SPH code, and model the NS with a stiff (index G=3…
A Central Engine for Cosmic Gamma-Ray Burst Sources
M. A. Ruderman, L. Tao, W. Kluzniak
One of a family previously proposed ``central engines'' for cosmic gamma-ray burst sources (Kluźniak & Ruderman 1998) is considered in some detail. A steadily accreting Gaus…
