Description:
When the solar wind hits Jupiter's magnetic field, it creates a long magnetotail trailing behind the planet that channels material out of the Jupiter system. The New Horizons spacecraft traversed the length of the jovian magnetotail to 〉2500 jovian radii (RJ; 1 RJ identical with 71,400 kilometers), observing a high-temperature, multispecies population of energetic particles. Velocity dispersions, anisotropies, and compositional variation seen in the deep-tail (greater, similar 500 RJ) with a approximately 3-day periodicity are similar to variations seen closer to Jupiter in Galileo data. The signatures suggest plasma streaming away from the planet and injection sites in the near-tail region (approximately 200 to 400 RJ) that could be related to magnetic reconnection events. The tail structure remains coherent at least until it reaches the magnetosheath at 1655 RJ.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McNutt, R L Jr -- Haggerty, D K -- Hill, M E -- Krimigis, S M -- Livi, S -- Ho, G C -- Gurnee, R S -- Mauk, B H -- Mitchell, D G -- Roelof, E C -- McComas, D J -- Bagenal, F -- Elliott, H A -- Brown, L E -- Kusterer, M -- Vandegriff, J -- Stern, S A -- Weaver, H A -- Spencer, J R -- Moore, J M -- New York, N.Y. -- Science. 2007 Oct 12;318(5848):220-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Applied Physics Laboratory, Johns Hopkins University, Laurel, MD 20723, USA. ralph.mcnutt@jhuapl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17932283" target="_blank"〉PubMed〈/a〉
