A tentative identification of Jovian global oscillations

Astronomy and Astrophysics (1991)

B. Mosser D. Gautier F. X. Schmider P. Delache

The identification of the Jovian frequency spectrum obtained by Schmider et al. (1990, 1991) is proposed, from Doppler shift observations of the solar sodium D line reflected by the planet, as a signature of Jovian global pressure modes. This spectrum, derived from 4 nights of observations, presents high-amplitude peaks whose origin is undoubtedly not noise, but it suffers from the daily interruption in the observations. Echelle diagram analysis has allowed the determination of a regular pattern, corresponding to the regularity indicatged by the asymptotic theory revised for Jovian seismology

Solar gravity modes from ACRIM/SMM irradiance data.

C. Fröhlich P. Delache

The record of 280 days of continuous data of the ACRIM radiometer on board the Solar Maximum Mission satellite is analyzed in the frequency range from 10 to 80 micro Hz. Gravity modes of degree one and two with orders from about 10 to several hundreds can be localized. A statistical method to determine the fundamental period T sub 0 and the rate of rotation upsilon sub R as seen by rotational splitting is described and the results for 33.5 T sub 0 45.5 minutes and 0.4 upsilon sub R micro Hz are presented. They indicate a rather high T sub 0 and it cannot be excluded that it is above the upper limit analyzed.
