Gravitational Waves: Just Plane Symmetry

We present some remarkable properties of the symmetry group for gravitational plane waves. Our main observation is that metrics with plane wave symmetry satisfy every system of generally covariant vacuum field equations except the Einstein equations. The proof uses the homothety admitted by metrics with plane wave symmetry and the scaling behavior of generally covariant field equations. We also...

Quantization of pure gravitational plane waves

Pure gravitational plane waves are considered as a special case of spacetimes with two commuting spacelike Killing vector elds. Starting with a midisuperspace that describes this kind of spacetimes, we introduce gaugexing and symmetry conditions that remove all non-physical degrees of freedom and ensure that the classical solutions are plane waves. In this way, we arrive at a reduced model with...

Conformal geometry of gravitational plane waves

It is well known that the conformal group of a non-flat vacuum pp-wave is at most 7-dimensional. Here we explicitly determine all solutions with a 7-dimensional group in three particular families of gravitational plane waves. All of them are exact solutions in terms of elementary functions. Furthermore, it turns out that a gravitational plane wave with a 6-dimensional homothety group (larger th...

Cataclysmic variables as sources of gravitational waves

General relativity predicts that binary systems of stars produce gravitational waves of significant intensity. Here we are particularly interested in the cataclysmic variable binaries (CVs). These systems emit low frequency gravitational waves, f < 10−3Hz. We present here a catalog of CVs and argue that part of them are capable of being detected by the Laser Interferometer Space Antenna (LISA).
