TL;DR: Data from the first occultations by Pluto since 1988 are reported and it is found that, during the intervening 14 years, there seems to have been a doubling of the atmospheric pressure, a probable seasonal effect on Pluto.
Journal ArticleDOI
Spectro-imaging observations of Jupiter's 2-μm auroral emission. I. H3+ distribution and temperature
E. Raynaud,E. Lellouch,Jean-Pierre Maillard,G. R. Gladstone,J. H. Waite,Bruno Bézard,Pierre Drossart,T. Fouchet +7 more
TL;DR: In this paper, the authors report on spectro-imaging infrared observations of Jupiter's auroral zones, acquired in October 1999 and October 2000 with the FTS/BEAR instrument at the Canada-France-Hawaii Telescope.
Journal ArticleDOI
A re-analysis of the 1971 Beta Scorpii occultation by Jupiter: study of temperature fluctuations and detection of wave activity
TL;DR: In this article, a wavelet analysis of the temperature profiles was performed to identify the dominant modes of wave activity and compare the reconstructed temperature fluctuations to model-generated gravity waves in the jovian atmosphere.
Journal ArticleDOI
The 10 October 1999 HIP 9369 occultation by the northern polar region of Jupiter: ingress and egress lightcurves analysis
E. Raynaud,Pierre Drossart,K. Matcheva,Bruno Sicardy,William B. Hubbard,F. Roques,Th Widemann,G. R. Gladstone,J. H. Waite,D. Nadeau,P. Bastien,René Doyon,R. E. Hill,Marcia J. Rieke,Mark S. Marley +14 more
TL;DR: In this paper, the authors estimate the errors on the profiles due to the uncertainties of the inversion method and compare the value of the temperature at the deepest level probed (∼ 50 μbar) with previous observations.
