R-modes of accreting hyperon stars as persistent sources of gravitational waves
Mohit Nayyar, Benjamin J. Owen
The -modes of accreting neutron stars could be a detectable source of persistent gravitational waves if the bulk viscosity of the stellar matter can prevent a thermal runaway. T…
Search for gravitational wave bursts in LIGO's third science run
LIGO Scientific Collaboration
We report on a search for gravitational wave bursts in data from the three LIGO interferometric detectors during their third science run. The search targets subsecond bursts in the…
Upper Limits on a Stochastic Background of Gravitational Waves
LIGO Scientific Collaboration, B. Abbott
The Laser Interferometer Gravitational Wave Observatory (LIGO) has performed a third science run with much improved sensitivities of all three interferometers. We present an analys…
Observational constraints on hyperons in neutron stars
Benjamin D. Lackey, Mohit Nayyar, Benjamin J. Owen
The possibility that neutron stars may contain substantial hyperon populations has important implications for neutron-star cooling and, through bulk viscosity, the viability of the…
Binary black hole initial data from matched asymptotic expansions
Nicolas Yunes, Wolfgang Tichy, Benjamin J. Owen +1
We present an approximate metric for a binary black hole spacetime to construct initial data for numerical relativity. This metric is obtained by asymptotically matching a post-New…
Maximum elastic deformations of compact stars with exotic equations of state
Benjamin J. Owen
I make the first estimates of maximum elastic quadrupole deformations sustainable by alternatives to conventional neutron stars. Solid strange quark stars might sustain maximum ell…
