DESCRIPTION:"Exploring harmonies between giant planets and their rings"\n\n
  \n\nAbstract: Planetary rings are exquisitely sensitive probes of gravita
 tional fields and so can provide insights into the deep internal structure
  and dynamics of their host planets. In particular\, Saturn's rings contai
 n an array of tightly wound spiral patterns that are generated by normal m
 ode oscillations and other asymmetries within that planet's interior. The 
 observable properties of these ring patterns have already yielded the freq
 uencies of many planetary normal modes\, which have revealed that Saturn l
 ikely has a diffuse core and clarified how fast different parts of the pla
 net rotate. At the same time\, unexpected trends in the amplitudes or thes
 e normal modes and other time-variable patterns in the rings hint that Sat
 urn has more complex internal dynamics than previously anticipated. More r
 ecently\, efforts have started to determine whether ring structures could 
 provide useful information about the internal structures of Uranus and Nep
 tune\, whose interiors are much less well understood. While a future missi
 on may be needed to fully realize the potential of ring seismology with th
 ese planets\, there are already hints of potentially interesting signals i
 n the currently available data that merit a closer look.
