Toward Early-Warning Detection of Gravitational Waves from Compact Binary Coalescence
Detection Gravitational Waves Compact Binary Coalescence
2011/10/9
Rapid detection of compact binary coalescence with a network of advanced gravitational-wave detectors will offer a unique opportunity for multi-messenger astronomy. Prompt detection alerts for the ast...
Astrometric Image Centroid Displacements due to Gravitational Microlensing by the Ellis Wormhole
Astrometric Image Centroid Displacements due to Gravitational Microlensing by the Ellis Wormhole
2011/10/17
Continuing work initiated in an earlier publication (Abe, ApJ, 725 (2010) 787), we study the gravitational microlensing effects of the Ellis wormhole in the weak-field limit. First, we find a suitable...

two-layer Maclaurin ellipsoids: Application to planets and satellites
2011/10/12
The exact solution for the shape and gravitational field of a rotating two-layer Maclaurin ellipsoid of revolution is compared with predictions of the theory of figures up to third order in the small ...
The impact of a stochastic gravitational-wave background on pulsar timing parameters
impact stochastic gravitational-wave background timing parameters
2011/10/12
Gravitational waves are predicted by Einstein's theory of general relativity as well as other theories of gravity. The rotational stability of the fastest pulsars means that timing of an array of thes...

2009/5/22
Astrophysicists looking for gravitational waves should set their sights on mountainous neutron stars, according to a new numerical study by researchers in the US. The study also suggests that the crus...
In this paper differential equation of relative rotation of a body
in closed Keplerian orbit has been derived. Effects of the gravitational moment
and of the orbit on this rotation are included by u...
