When you lose something, you always find it in the last place you look. If only you looked there first.....hmmm... These guys looked right at the three biggest things in the solar system, and found some ready and waiting gravitational wave data. They think. SEE:http://arxiv.org/abs/1412.0992


looks like the instrumental calibration reaches specs...I can't access the website for the reference 14 to P. Gaulme et al " The Detection of Jovian seismic waves: a new probe of its interior structure.

Nice catch. Yes, if we see vibrational modes in several moons which are coordinated and proportional to the mass of each moon, it is reasonable to assume such vibrations are due to a common source. The sticky part, is determining whether the source of the vibrations is within the system: If Saturn is vibrating, each of the moons will pick up these subtle shifts in the Saturn system center-of-gravity. We would have to have time-stamped data to very high precision to eliminate local gravity field variance from the equation.

Another problem is assuring the small vibrations are not associated with an earth-based vibration mode; or seeing conditions.

That said, it is certainly worth a shot to do a coordinated study of vibrational modes when Jupiter and Saturn are in the same lens field: If first Saturn rings, and about four minutes later Jupiter's moons chime in at the same frequency - yes, we do have a winner.
