Stellar interferometry for gravitational waves

Atom Interferometry for Detection of Gravitational Waves

Stellar Collapse and Gravitational Waves

The new generation of gravitational wave (GW) detectors have the potential to open a novel window onto the violent dynamics of core collapse. Although it is certain that core collapse events generate gravitational radiation, understanding the characteristics of the radiation — whether it can be measured with these detectors, and the best way to go about doing so — is a challenging problem. In t...

Laser interferometry for the detection of gravitational waves

Results are now appearing from the first generation of long baseline gravitational wave detectors that use laser interferometry for motion sensing. In this short review the history of the field will be briefly discussed, and the principles of the novel laser interferometry developed will be outlined in the context of present and future instruments.

Gravitational Waves from Axisymmetric, Rotating Stellar Core Collapse

We have carried out an extensive set of two-dimensional, axisymmetric, purely-hydrodynamic calculations of rotational stellar core collapse with a realistic, finite-temperature nuclear equation of state and realistic massive star progenitor models. For each of the total number of 72 different simulations we performed, the gravitational wave signature was extracted via the quadrupole formula in ...

Resonant growth of stellar oscillations by incident gravitational waves

Stellar oscillation under the combined influences of incident gravitational wave and radiation loss is studied in a simple toy model. The star is approximated as a uniform density ellipsoid in the Newtonian gravity including radiation damping through quadrupole formula. The time evolution of the oscillation is significantly controlled by the incident wave amplitude h, frequency ν and damping ti...
