Query: The effect of Jupiter oscillations on Juno gravity measurements   Seismology represents a unique method to probe the interiors of giant
planets. Recently, Saturn's f-modes have been indirectly observed in its rings,
and there is strong evidence for the detection of Jupiter global modes by means
of ground-based, spatially-resolved, velocimetry measurements. We propose to
exploit Juno's extremely accurate radio science data by looking at the gravity
perturbations that Jupiter's acoustic modes would produce. We evaluate the
perturbation to Jupiter's gravitational field using the oscillation spectrum of
a polytrope with index 1 and the corresponding radial eigenfunctions. We show
that Juno will be most sensitive to the fundamental mode ($n=0$), unless its
amplitude is smaller than 0.5 cm/s, i.e. 100 times weaker than the $n \sim\ 4 -
11$ modes detected by spatially-resolved velocimetry. The oscillations yield
contributions to Juno's measured gravitational coefficients similar to or
larger than those expected from shallow zonal winds (extending to depths less
than 300 km). In the case of a strong f-mode (radial velocity $\sim$ 30 cm/s),
these contributions would become of the same order as those expected from deep
zonal winds (extending to 3000 km), especially on the low degree zonal
harmonics, therefore requiring a new approach to the analysis of Juno data.
