perturbative method for treating general relativistic rotating neutron
Author(s): A.G. Katelouzos, V.S. Geroyannis, V. S (Poster)
Weber & Glendenning (1992, ApJ, 390, 541) have
confirmed by detailed computations and comparisons the applicability of
Hartle's perturbative method on treating general relativistic rotating
neutron star models (Hartle & Thorne 1968, ApJ, 153, 807, and
references therein) down to a rotational period of ~0.5 ms; so, Hartle's
method proves to be reliable and useful even for such fast rotations. In
the present paper, we examine the possibility of further improving the
numerical results by combining Hartle's perturbative method with the
algorithms used in the so-called "complex-plane strategy"
(Geroyannis 1988, Apj, 327, 273).
