Waves in Astrophysics

A diverse group of astronomers, physicists, and mathematicians discuss chaos in observational data of variable stars; unstable long wavelenth MHD waves; the interstellar medium; Alfven waves and interstellar turbulence; sinuous oscillations and steady warps of polytropic disks; waves in shock-bounded slabs; normal modes and continuous spectra; vorticity and mixing in disks; bending waves in flattened stellar systems; global wave patterns in galaxies; invariant spectra of dynamical systems time-periodic potentials; Lyapunov numbers in pulsating systems; Arnold diffusion in an oscillator chain; universal properties of escape; counterrotating bars; shadowing and noise in nonhyperbolic systems; relativistic accretion disks; tidal perturbation of a gaseous disk; magnetized accretion disks; structural stability; nonlinear stellar pulsation; tidal pertubations, gravitational amplifacation and galaxy spiral arms; gasous vortices in barred spiral galaxies; and the barred spiral gallaxy NGC 1398.
