Simultaneous Chandra X ray, Hubble Space Telescope ultraviolet, and Ulysses radio observations of Jupiters aurora
[1] Observations of Jupiter carried out by the Chandra Advanced CCD Imaging Spectrometer (ACIS-S) instrument over 24–26 February 2003 show that the auroral X-ray spectrum consists of line emission consistent with high-charge states of precipitating ions, and not a continuum as might be expected from bremsstrahlung. The part of the spectrum due to oxygen peaks around 650 eV, which indicates a hi...
متن کاملMorphology and time variability of Io's visible aurora
Clear-filter imaging of Io during the Galileo nominal and extended missions recorded diffuse auroral emissions in 16 distinct observations taken during 14 separate eclipses over a two year period. These images how that the morphology and time variability of the visible aurora have several similarities to Io's far ultraviolet emissions. The orbital eading hemisphere ofIo is consistently brighter...
متن کاملThe Io UV footprint: Location, inter-spot distances and tail vertical extent
[1] The Io footprint (IFP) consists of one or several spots observed in both jovian hemispheres and is related to the electromagnetic interaction between Io and the magnetosphere. These spots are followed by an auroral curtain, called the tail, extending more than 90 longitude in the direction of planetary rotation. We use recent Hubble Space Telescope images of Jupiter to analyze the location ...
متن کاملThe 3‐D extent of the Io UV footprint on Jupiter
[1] The Io footprint (IFP) is the auroral signature of the electromagnetic interaction between Io and Jupiter’s magnetosphere. It consists of several spots followed by an extended tail, which are located close to the feet of the magnetic field lines connecting Io to Jupiter. The size of the main spot is a controversial issue, and previously published values range from ∼400 to ∼8000 km. However,...
متن کاملPetascale IO Using The Adaptable IO System
ADIOS, the adaptable IO system, has demonstrated excellent scalability to 29,000 cores. With the introduction of the XT5 upgrades to Jaguar, new optimizations are required to successfully reach 140,000+ cores. This paper explains the techniques employed and shows the performance levels attained.
