On the Oscillations of Jupiter as Observed by Voyager 2

Abstract

Data recorded from Voyager 2 in 1979 during closest approach to Jupiter is prepared and analyzed for evidence of Jovian modal forcing. Comparisons are drawn between the data set in question and previously performed analysis by Mosser et al. [27], [29], [6] and also to the models presented by Gudkova and Zharkov in [19]. The theory of stationary processes and multitaper spectrum estimation are em- ployed extensively in the analysis, along with intensive use of the harmonic frequency variance test as a tool for separating signal from noise. The splitting of low-order p-modes is briefly examined and found to be in-line with that discovered earlier by Mosser et al..
