Shells around black holes: the effect of freely specifiable quantities in Einstein's constraint equations
Keith Matera, Thomas W. Baumgarte, Eric Gourgoulhon
We solve Einstein's constraint equations in the conformal thin-sandwich decomposition to model thin shells of non-interacting particles in circular orbit about a non-rotating black…
EOS of dense matter and fast rotation of neutron stars
J. L. Zdunik, P. Haensel, M. Bejger +1
Recent observations of XTE J1739-285 suggest that it contains a neutron star rotating at 1122 Hz. Such rotational frequency would be the first for which the effects of rotation are…
The energy release--stellar angular momentum independence in rotating compact stars undergoing first-order phase transitions
M. Bejger, J. L. Zdunik, P. Haensel +1
We present the general relativistic calculation of the energy release associated with a first order phase transition (PT) at the center of a rotating neutron star (NS). The energy…
Trapping Horizons as inner boundary conditions for black hole spacetimes
J. L. Jaramillo, E. Gourgoulhon, I. Cordero-Carrion +1
We present a set of inner boundary conditions for the numerical construction of dynamical black hole space-times, when employing a 3+1 constrained evolution scheme and an excision…
Strong first-order phase transition in a rotating neutron star core and the associated energy release
J. L. Zdunik, M. Bejger, P. Haensel +1
We calculate the energy release associated with a strong first-order phase transition, from normal phase N to an "exotic" superdense phase S, in a rotating neutron star. Such a pha…
Construction of initial data for 3+1 numerical relativity
Eric Gourgoulhon
This lecture is devoted to the problem of computing initial data for the Cauchy problem of 3+1 general relativity. The main task is to solve the constraint equations. The conformal…
