Vertical Structure of Jupiter's Atmosphere at the Galileo Probe Entry Latitude
Beebe, R. F.; Chanover, N. J.; Kuehn, D. M.
The vertical structure of Jupiter's atmosphere is examined to better characterize the latitudinal region of the Galileo probe entry site: +5°-10° planetographic latitude. One-hundred Hubble Space Telescope images of Jupiter taken with the 893- and 953-nm filters on 13 and 17 February 1995, 5 October 1995, and 14 May 1996 are analyzed, and a two-cl…
NOTE: Saturn Ring-Plane Crossing, May 1995: Pole Precession and Ring Thickness
Bosh, Amanda S.; Rivkin, Andrew S.; Percival, Jeffrey W. +2 more
On 22 May 1995, as the Earth crossed through Saturn's ring-plane, we used the Wide Field Planetary Camera 2 on the Hubble Space Telescope to image Saturn and its rings for 10 hr centered near the predicted time of ring-plane crossing. By performing photometry on the rings, we find that the time of ring-plane crossing is later than the nominal pred…
Impact of Comet Shoemaker-Levy 9—Size, Origin, and Plumes: Comparison of Numerical Analysis with Observations
Takata, Toshiko; Ahrens, Thomas J.
Numerical results of impact of Comet Shoemaker-Levy 9 (SL9) on Jupiter are compared with observational phenomena to investigate the size and origin of SL9 and impact features. Plume evolution is simulated numerically for 0.4- and 2.0-km-diameter (D) impactors. Analytical estimates indicate that the maximum plume heights are proportional to (D/lnD)…
