Searching for comets encountering Jupiter . Second campaign observations and further constraints on the size of the Jupiter familypopulation

| 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...

Voyager Spacecraft Radio Observations of Jupiter: Initial Cruise Results

Planetary radio astronomy observations from voyager 2 near jupiter.

The Voyager 2 Planetary Radio Astronomy experiment to Jupiter has confirmed and extended to higher zenomagnetic latitudes results from the identical experiment carried by Voyager 1. The kilometric emissions discovered by Voyager 1 often extended to 1 megahertz or higher on Voyager 2 and often consisted of negatively or, less frequently, positively drifting narrowband bursts. On the basis of ten...

New Jupiter and Saturn formation models meet observations

The wealth of observational data about Jupiter and Saturn provides strong constraints to guide our understanding of the formation of giant planets. The size of the core and the total amount of heavy elements in the envelope have been derived from internal structure studies by Saumon & Guillot (2004). The atmospheric abundance of some volatile elements has been measured in situ by the Galileo pr...

Processes of auroral thermal structure at Jupiter: Analysis of multispectral temperature observations with the Jupiter Thermosphere General Circulation Model

[1] We use our three-dimensional Jupiter Thermosphere General Circulation Model (JTGCM) to quantify thermal processes that take place in the auroral thermosphere. These processes tend to control the thermal budget in the Jovian ovals and polar caps and maintain thermospheric temperatures consistent with those derived from multispectral observations of Jupiter’s aurora. The main heat source in t...
