From Wormholes to the Warp Drive: Using theoretical physics to place ultimate bounds on technology
William A. Hiscock
The serious study of such science fiction staples as wormholes, time travel, and the warp drive, as a means of understanding and constraining possible realistic solutions within Ge…
Precession of Isolated Neutron Stars
Bennett Link
I summarize the evidence for precession of isolated neutron stars and theoretical effort to understand the observations. I discuss factors that might set the precession period, des…
The Crustal Rigidity of a Neutron Star, and Implications for PSR 1828-11 and other Precession Candidates
Curt Cutler, Greg Ushomirsky, Bennett Link
We calculate the crustal rigidity parameter, b, of a neutron star (NS), and show that b is a factor 40 smaller than the standard estimate due to Baym & Pines (1971). For a NS with…
LISA, binary stars, and the mass of the graviton
Curt Cutler, William A. Hiscock, Shane L. Larson
We extend and improve earlier estimates of the ability of the proposed LISA (Laser Interferometer Space Antenna) gravitational wave detector to place upper bounds on the graviton m…
The LISA Response Function
Neil J. Cornish, Louis J. Rubbo
The orbital motion of the Laser Interferometer Space Antenna (LISA) introduces modulations into the observed gravitational wave signal. These modulations can be used to determine t…
The information content of gravitational wave harmonics in compact binary inspiral
Ronald W. Hellings, Thomas A. Moore
The nonlinear aspect of gravitational wave generation that produces power at harmonics of the orbital frequency, above the fundamental quadrupole frequency, is examined to see what…
