We identify a subsample of the recently detected extrasolar planets that is minimally affected by the selection effects of the Doppler detection method. With a simple analysis we quantify trends in the surface density of this subsample in the period-M sin(i) plane. A modest extrapolation of these trends puts Jupiter in the most densely occupied region of this parameter space, thus indicating th...

Introduction: The Juno mission is the second mission in NASA’s New Frontiers program. Launched in August 2011, Juno arrives at Jupiter in 2016 for a one year prime mission. Juno science goals include the study of Jupiter’s origin, interior structure, deep atmosphere, aurora and magnetosphere. Juno’s orbit around Jupiter is a polar elliptical orbit with perijove approximately 5000 km above the v...

to determine suitable pepper cultivars with high quantitative and qualitative characteristics adapted to the climate of sistan, an experiment was conducted in zahak experimental station, zabol, using rcbd with four replications in two years. in this experiment, four sweet pepper, five green pepper and three salad pepper cultivars were evaluated individually. the results showed significant diffe...

It has long been assumed that the planet Jupiter acts as a giant shield, significantly lowering the impact rate of minor bodies on Earth. However, until recently, very little work had been carried out examining the role played by Jupiter in determining the frequency of such collisions. In this work, the third of a series of papers, we examine the degree to which the impact rate on Earth resulti...

We present calculations of magnetic potential functions associated with the perturbation of Saturn’s planetary magnetic field by a rotating, equatorially-situated disc of plasma. Such structures are central to the dynamics of the rapidly rotating magnetospheres of Saturn and Jupiter. They are ‘fed’ internally by sources of plasma from moons such as Enceladus (Saturn) and Io (Jupiter). For these...

To date, reflectance spectra of Jupiter Trojan asteroids have revealed no distinctive absorption features. For this reason, the surface composition of these objects remains a subject of speculation. Spectra have revealed, however, that the Jupiter Trojan asteroids consist of two distinct sub-populations which differ in the optical to near-infrared colors. The origins and compositional differenc...

A study is made of the UV reflection spectrum of Jupiter as measured by the International Ultraviolet Explorer. Detailed modeling reveals the mixing ratios of C2H2 , C2H6 , and C4 H2 to be (1.0 ± 0.1) x 101 , (6.6 ± 5.3) x 106 , and (2.9 ± 2.0) x 1010, respectively, in the pressure region between ,..., 3 and 40 mbar. Upper limits in this pressure region for the mixing ratios of C2H4 and NH3 wer...

This paper describes the design, implementation, and experimental evaluation of a modular and extensible Java r © Virtual Machine (JVM) infrastructure, called Jupiter. The infrastructure is intended to serve as a vehicle for our research on scalable JVM architectures for a 128-processor cluster of PC workstations, with support for shared memory in software. Jupiter is constructed, using a build...

After nearly four years of space flight, the Galileo spacecraft is finally on a direct trajectory to its final destination, Jupiter. It has taken three planetary gravity assists to achieve the energy necessary for Galileo to reach Jupiter. This Venus-Earth-Earth gravity assist route is referred to as the VEEGA trajectory. Each gravity assist required precise spacecraft delivery to the proper ai...

Gravitational capture can be used to explain the existence of the irregular satellites of giants planets. However, it is only the first step since the gravitational capture is temporary. Therefore, some kind of non-conservative effect is necessary to to turn the temporary capture into a permanent one. In the present work we study the effects of Jupiter mass growth for the permanent capture of r...
