    Q: A rogue star, primarily known as an intergalactic star, is a star that has escaped the gravitational pull of its home galaxy and is moving independently in or towards the intergalactic void. More loosely, any star in an unusual location or state of motion may be termed a rogue star. The outer solar system begins somewhere in the asteroid belt, beyond Mars. The first major outpost of this vast realm is Jupiter, the giant planet. Orbiting at a mean distance of million km from the Sun, Jupiter is the largest of the Sun’s family of planetary companions, having a volume approximately times that of Earth. Jupiter is not merely a single large planet, however; it .

    The Galileo’s notes summarizing his first observations of the Jovian density, which is the mass divided by the volume, provides satellites Io, Europa, Ganymede, and Callisto in January important clues to the composition and interior structure of a were made on a piece of scratch paper containing the draft of a planetary body.5/5(1).

    Analyses based on the combination of the magnetometer data, the Cassini Plasma Spectrometer and the Radio and Plasma Wave Spectrometer revealed that when the Orange Moon is temporarily outside of the magnetosphere of the Ringed Planet, the atmosphere of Titan keeps a memory of the magnetic field of the plasma that is found around the Gas Giant.

[1] Cassini magnetic field observations show that few‐nT oscillations near the planetary rotation period, first observed in Pioneer‐11 and Voyager‐1 and ‐2 fly‐by data, are essentially ubiquitous in Saturn's magnetosphere, though their character differs between the quasi‐dipolar ring current region and the dawn tail.

Because Jupiter's magnetic field is tilted by 10 degrees relative to its rotation axis, the plasma sheet and the magnetic equator appear to move up and down as seen from Europa, with a period of hours (i.e., the synodic period corresponding to the hour rotation rate of Jupiter's magnetic field and Europa's day rotation rate).

The oblique whistler waves have been studied having k vector at an angle to magnetic field for a generalized distribution function reducible to bi-maxwellian and loss-cone. The dispersion relation and growth rate have been obtained for oblique whistler mode instability incorporating the trajectory of the particles, in the presence of perpendicular a-c electric field Cited by: 6.

1 Introduction. Electromagnetic waves near the ion cyclotron frequency and its harmonics have been observed in the Earth's magnetosphere, both in the inner magnetosphere and in the plasma sheet boundary layer (PSBL) [see, e.g., Denton et al.,and references therein].In all reported cases harmonic waves propagated perpendicular or at a very large angle to the Cited by: Unfortunately, this book can't be printed from the OpenBook.

magnetic field of Jupiter through electromagnetic induction [Khurana et al. ]. In this process, eddy currents are generated on the surface of a conductor to shield its interior from changing external electric and magnetic fields. The eddy currents generate their own magnetic field—called the induction field—external to the conductor.

4 PASSAGE TO A RINGED WORLD In traveling to Saturn with Cassini– Huygens, we will also be satisfying a cultural desire to obtain new knowl-edge. This drive is very strong be-cause modern society places a very high value on knowledge. For exam-ple, the whole field of education is fo-cused on transferring knowledge to new generations.

At the same time the plasma wave analyzer recorded bursts of radio noise indicative of electrons interacting with a magnetosphere. Taken together the data suggested that Ganymede was a “moon with magnetism” and possessed its own internal, dipole, magnetic field strong enough to counteract the local field from Jupiter, creating a.

Next, the main findings of the observations by Hubble and Galileo are : Huybrighs, Hans, L.F.The first publication (Kivelson et al. b) reveals us strongly promoting the view that Io has an internal dynamo-generated magnetic field.
