Comparison of advanced gravitational-wave detectors
Gregory M Harry, Janet L Houser, Kenneth A Strain
We compare two advanced designs for gravitational-wave antennas in terms of their ability to detect two possible gravitational wave sources. Spherical, resonant mass antennas and i…
Gravitational Radiation from Rotational Instabilities in Compact Stellar Cores with Stiff Equations of State
Janet L. Houser, Joan M. Centrella
We carry out 3-D numerical simulations of the dynamical instability in rapidly rotating stars initially modeled as polytropes with n = 1.5, 1.0, and 0.5. The calculations are done…
Simulations of Nonaxisymmetric Instability in a Rotating Star: A Comparison Between Eulerian and Smooth Particle Hydrodynamics
Scott C. Smith, Janet L. Houser, Joan M. Centrella
We have carried out 3-D numerical simulations of the dynamical bar instability in a rotating star and the resulting gravitational radiation using both an Eulerian code written in c…
Gravitational Radiation from Nonaxisymmetric Instability in a Rotating Star
J. L. Houser, J. M. Centrella, S. C. Smith
We present the first calculations of the gravitational radiation produced by nonaxisymmetric dynamical instability in a rapidly rotating compact star. The star deforms into a bar s…
