Beschreibung:
Seven particles captured by the Stardust Interstellar Dust Collector and returned to Earth for laboratory analysis have features consistent with an origin in the contemporary interstellar dust stream. More than 50 spacecraft debris particles were also identified. The interstellar dust candidates are readily distinguished from debris impacts on the basis of elemental composition and/or impact trajectory. The seven candidate interstellar particles are diverse in elemental composition, crystal structure, and size. The presence of crystalline grains and multiple iron-bearing phases, including sulfide, in some particles indicates that individual interstellar particles diverge from any one representative model of interstellar dust inferred from astronomical observations and theory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Westphal, Andrew J -- Stroud, Rhonda M -- Bechtel, Hans A -- Brenker, Frank E -- Butterworth, Anna L -- Flynn, George J -- Frank, David R -- Gainsforth, Zack -- Hillier, Jon K -- Postberg, Frank -- Simionovici, Alexandre S -- Sterken, Veerle J -- Nittler, Larry R -- Allen, Carlton -- Anderson, David -- Ansari, Asna -- Bajt, Sasa -- Bastien, Ron K -- Bassim, Nabil -- Bridges, John -- Brownlee, Donald E -- Burchell, Mark -- Burghammer, Manfred -- Changela, Hitesh -- Cloetens, Peter -- Davis, Andrew M -- Doll, Ryan -- Floss, Christine -- Grun, Eberhard -- Heck, Philipp R -- Hoppe, Peter -- Hudson, Bruce -- Huth, Joachim -- Kearsley, Anton -- King, Ashley J -- Lai, Barry -- Leitner, Jan -- Lemelle, Laurence -- Leonard, Ariel -- Leroux, Hugues -- Lettieri, Robert -- Marchant, William -- Ogliore, Ryan -- Ong, Wei Jia -- Price, Mark C -- Sandford, Scott A -- Sans Tresseras, Juan-Angel -- Schmitz, Sylvia -- Schoonjans, Tom -- Schreiber, Kate -- Silversmit, Geert -- Sole, Vicente A -- Srama, Ralf -- Stadermann, Frank -- Stephan, Thomas -- Stodolna, Julien -- Sutton, Stephen -- Trieloff, Mario -- Tsou, Peter -- Tyliszczak, Tolek -- Vekemans, Bart -- Vincze, Laszlo -- Von Korff, Joshua -- Wordsworth, Naomi -- Zevin, Daniel -- Zolensky, Michael E -- 30714 Stardust@home dusters -- New York, N.Y. -- Science. 2014 Aug 15;345(6198):786-91. doi: 10.1126/science.1252496.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Space Sciences Laboratory, University of California at Berkeley, Berkeley, CA, USA. westphal@ssl.berkeley.edu. ; Materials Science and Technology Division, Naval Research Laboratory, Washington, DC, USA. ; Advanced Light Source, Lawrence Berkeley Laboratory, Berkeley, CA, USA. ; Geoscience Institute, Goethe University Frankfurt, Frankfurt, Germany. ; Space Sciences Laboratory, University of California at Berkeley, Berkeley, CA, USA. ; State University of New York at Plattsburgh, Plattsburgh, NY, USA. ; Jacobs Technology/ESCG, NASA Johnson Space Center (JSC), Houston, TX, USA. ; Institut fur Geowissenschaften, University of Heidelberg, Germany. ; Institut des Sciences de la Terre, Observatoire des Sciences de l'Univers de Grenoble, Grenoble, France. ; Institut fur Raumfahrtsysteme (IRS), University of Stuttgart, Stuttgart, Germany.
