Gravitational Instability in Radiation Pressure Dominated Backgrounds
I consider the physics of gravitational instabilities in the presence of dynamically important radiation pressure and gray radiative diffusion, governed by a constant opacity κ. For any non-zero radiation diffusion rate on an optically-thick scale k−1, the medium is unstable unless the classical gas-only isothermal Jeans criterion is satisfied. If the radiation acoustic sound crossing timescale...
متن کاملGravitational radiation from the r-mode instability
The instability in the r-modes of rotating neutron stars can (in principle) emit substantial amounts of gravitational radiation (GR) which might be detectable by LIGO and similar detectors. Estimates are given here of the detectability of this GR based the non-linear simulations of the r-mode instability by Lindblom, Tohline and Vallisneri. The burst of GR produced by the instability in the rap...
متن کاملCosmological Gravitational Wave Backgrounds
An overview is presented of possible cosmologically distant sources of gravitational wave backgrounds, especially those which might produce detectable backgrounds in the LISA band between 0.1 and 100 mHz. Examples considered here include inflation-amplified vacuum fluctuations in inflaton and graviton fields, bubble collisions in first-order phase transitions, Goldstone modes of classical self-...
متن کاملGravitational radiation from nonaxisymmetric instability in a rotating star.
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 shape, shedding ∼ 4% of its mass and ∼ 17% of its angular momentum. The gravitational radiation is calculated in the quadrupole approximation. For a mass M ∼ 1.4 M⊙ and radius R ∼ 10 km, the gravitational waves have fr...
متن کاملStochastic backgrounds of gravitational waves
We review the motivations for the search of stochastic backgrounds of gravitational waves and we compare the experimental sensitivities that can be reached in the near future with the existing bounds and with the theoretical predictions.
