Origins of Solar System Dust Beyond Jupiter
The measurements of cosmic interplanetary dust by the instruments on board the Pioneer 10 and 11 spacecraft contain the dynamical signature of dust generated by Edgeworth-Kuiper Belt objects, as well as short period Oort Cloud comets and short period Jupiter family comets. While the dust concentration detected between Jupiter and Saturn is mainly due to the cometary components, the dust outside...
متن کاملThe Jupiter Twin HD 154345b
We announce the discovery of a twin of Jupiter orbiting the slightly metalpoor ([Fe/H] = −0.1) nearby (d= 18 pc) G8 dwarf HD 154345. This planet has a minimum mass of 0.95 MJup and a 9.2 year, circular orbit with radius 4.2 AU. There is currently little or no evidence for other planets in the system, but smaller or exterior planets cannot yet be ruled out. We also detect a ∼ 9-year activity cyc...
متن کاملThe observed Trojans and the global dynamics around the Lagrangian points of the Sun–Jupiter system
In this paper, we make a systematic study of the global dynamical structure of the Sun– Jupiter L4 tadpole region. The results are based on long-time simulations of the Trojans in the Sun, Jupiter, Saturn system and on the frequency analysis of these orbits. We give some initial results in the description of the resonant structure that guides the long-term dynamics of this region. Moreover, we ...
متن کاملOn the stability of the secular evolution of the planar Sun-Jupiter-Saturn-Uranus system
We investigate the long time stability of the Sun–Jupiter–Saturn–Uranus system by considering the planar, secular model. Our ethod may be considered as an extension of Lagrange’s theory for the secular motions. Indeed, concerning the planetary orbital evolutions, we improve the classical circular approximation by replacing it with a torus which is invariant up to order two in he masses; therefo...
متن کاملA Preliminary Jupiter Model
In anticipation of new observational results for Jupiter’s axial moment of inertia and gravitational zonal harmonic coefficients from the forthcoming Juno orbiter, we present a number of preliminary Jupiter interior models. We combine results from ab initio computer simulations of hydrogen-helium mixtures, including immiscibility calculations, with a new nonperturbative calculation of Jupiter’s...
