The Secular Evolution of a Close Ring–Satellite System: The Excitation of Spiral Bending Waves at a Nearby Gap Edge
The secular perturbations exerted by an inclined satellite orbiting in a gap in a broad planetary ring tends to excite the inclinations of the nearby ring particles, and the ring’s self–gravity can allow that disturbance to propagate away in the form of a spiral bending wave. The amplitude of this spiral bending wave is determined, as well as the wavelength, which shrinks as the waves propagate...
متن کاملThe Secular Evolution of a Close Ring–Satellite System: The Excitation of Spiral Density Waves at a Nearby Gap Edge
The Lagrange planetary equations are used to study to secular evolution of a small, eccentric satellite that orbits within a narrow gap in a broad, selfgravitating planetary ring. These equations show that the satellite’s secular perturbations of the ring will excite a very long-wavelength spiral density wave that propagates away from the gap’s outer edge. The amplitude of these waves, as well ...
متن کاملSecular Evolution of Spiral Galaxies
It is now a well established fact that galaxies undergo significant morphological transformation during their lifetimes, manifesting as an evolution along the Hubble sequence from the late to the early Hubble types. The physical processes commonly believed to be responsible for this observed evolution trend, i.e. the major and minor mergers, as well as gas accretion under a barred potential, th...
متن کاملArbitrary bending plasmonic light waves.
We demonstrate the generation of self-accelerating surface plasmon beams along arbitrary caustic curvatures. These plasmonic beams are excited by free-space beams through a two-dimensional binary plasmonic phase mask, which provides the missing momentum between the two beams in the direction of propagation and sets the required phase for the plasmonic beam in the transverse direction. We examin...
متن کاملBending waves in crumpled sheets.
Crumpled paper has recently emerged as a model for disordered media. Here we use wave propagation to probe aluminum foils crumpled into balls made by hand or into cylinders obtained by confinement in a container. Surprisingly, the raw dispersion relations appear to differ from sample to sample. They correspond to bending waves that follow an effective path that is shorter than the distance betw...
