An Exact, Three-Dimensional, Time-Dependent Wave Solution in Local Keplerian Flow
arXiv:astro-ph/0608429 · doi:10.1086/508320
Abstract
We present an exact three-dimensional wave solution to the shearing sheet equations of motion. The existence of this solution argues against transient amplification as a route to turbulence in unmagnetized disks. Moreover, because the solution covers an extensive dynamical range in wavenumber space, it is an excellent test of the dissipative properties of numerical codes.
