Possible evidence of p-modes in Cassini measurements of Saturn's gravity field
Steve Markham, Daniele Durante, Luciano Iess +1
We analyze the range rate residual data from Cassini's gravity experiment that cannot be explained with a static, zonally symmetric gravity field. In this paper we reproduce the da…

Constraining the effect of convective inhibition on the thermal evolution of Uranus and Neptune
Steve Markham, Dave Stevenson
The internal heat flows of both Uranus and Neptune remain major outstanding problems in planetary science. Uranus' surprisingly cold effective temperature is inconsistent with adia…

Excitation Mechanisms for Jovian Seismic Modes
Steve Markham, Dave Stevenson
Recent (2011) results from the Nice Observatory indicate the existence of global seismic modes on Jupiter in the frequency range between 0.7 and 1.5mHz with amplitudes of tens of c…
