The regions around the L4 and L5 Lagrangian points of Jupiter are populated by two large swarms of asteroids called the Trojans. They may be as numerous as the main-belt asteroids and their dynamics is peculiar, involving a 1:1 resonance with Jupiter. Their origin probably dates back to the formation of Jupiter: the Trojan precursors were planetesimals orbiting close to the growing planet. Diff...

In the early phase of the Solar System evolution, while the outer planets migrated due to their interaction with a planetesimal disk, Jupiter may have crossed the 2:1 mean motion resonance with Saturn. It is well known (Morbidelli et al. 2005) that this dynamical event has profound consequences on the evolution of an alleged initial Trojan population of Jupiter. In this paper, we analyse in det...

We study the effects of Jupiter mass growth in order to permanently capture prograde satellites. Adopting the restricted three-body problem, Sun-Jupiter-Particle, we performed numerical simulations backward in time while considering the decrease in Jupiter’s mass. We considered the particle’s initial conditions to be prograde, at pericenter, in the region 100R ≤ a ≤ 400R and 0 ≤ e ≤ 0.5. The re...

The deep interiors of Jupiter and Saturn consist of fluid, metallic hydrogen. In Jupiter the metallic hydrogen is uniformly mixed with helium. In Saturn, the incomplete solubility of helium may cause unmixing and energy release. In the interiors of Uranus and Neptune the fluid mixture (of hydrogen, helium, water, methane and ammonia) is metallic or ionic. The terrestral planetary cores are pred...

Anderson & Schubert (2007, Science, 317, 1384) proposed that Saturn’s rotation period can be ascertained by minimizing the dynamic heights of the 100 mbar isosurface with respect to the geoid; they derived a rotation period of 10h 32m 35s. We investigate the same approach for Jupiter to see if the Jovian rotation period is predicted by minimizing the dynamical heights of its isobaric (1 bar pre...

Three-dimensional numerical simulations of the atmospheric flow on giant planets using the primitive equations show that shallow thermal forcing confined to pressures near the cloud tops can produce deep zonal winds from the tropopause all the way down to the bottom of the atmosphere. These deep winds can attain speeds comparable to the zonal jet speeds within the shallow, forced layer; they ar...

OBJECTIVES We sought to evaluate the cost-effectiveness of applying the JUPITER (Justification for the Use of statins in Prevention: an Intervention Trial Evaluating Rosuvastatin) trial results into clinical practice. BACKGROUND The JUPITER trial found that rosuvastatin reduces vascular events in apparently healthy subjects with elevated high-sensitivity C-reactive protein (hs-CRP) but normal...

The 3:1 mean-motion resonance of the planar elliptic restricted three body problem (Sun-Jupiter-asteroid) is considered. The double numeric averaging is used to obtain the evolutionary equations which describe the long-term behavior of the asteroid's argument of pericentre and eccentricity. The existence of the adiabatic chaos area in the system's phase space is shown. The 3:1 mean-motion reson...

| The results from the second campaign of the search for comets in the vicinity of Jupiter are presented. As in the previous campaign, we nd no comets. This result is used to calculate upper limits on the size of the Jupiter family population of comets. The numbers found are the same as in the previous campaign, but have the advantage that the lack of complete discovery at the limiting magnitud...

We give an overview of our current understanding of the structure of gas giant planets, from Jupiter and Saturn to extrasolar giant planets. We focus on addressing what high-pressure laboratory experiments on hydrogen and helium can help to elucidate about the structure of these planets. Subject headings: planetary systems, Jupiter, Saturn
