Cancelled: DIX Planetary Science Seminar
Profound insights about the interior of Earth, Mars, and the Sun have come from traveling wave seismology, and varying degrees of normal mode (global) seismology. How can similar methods be applied in the outer solar system, and is there a breakthrough on the horizon? Giant planet interiors are typically studied with measurements of their static gravity fields and magnetic fields. I'll describe efforts to develop the third pillar offered by normal mode seismology, which has brought a surprising bounty of information about Saturn's structure thanks to Cassini ring seismology, and may be a crucial window into Uranus's interior in the era of the Uranus Orbiter and Probe. The next steps in this curious field may involve a mixture of ring science, gravitational (radio) seismology, and Doppler imaging.
