Synchrotron-based organics and mineralogical survey of threeStardust tracks
Wild2 particles captured in the Stardust cometary dustcollector exhibit remarkable diversity between and within individualparticle tracks in aerogel. Several particles studied during the StardustPreliminary Examination are, so far, unique in the collection[1]. Thereis an urgent need to survey particles in tracks and to target specificparticles for extraction and destructive analysis. Here we describe an inaerogel survey at the Advanced Light Source (LBNL) of three tracks usingsynchrotron-based Fourier Transform Infrared Spectroscopy (FTIR),microbeam X-ray fluorescence (microXRF), X-ray Absorption Near-EdgeSpectroscopy (microXANES), X-ray Diffraction (XRD), and ScanningTransmission X-ray Microscopy (STXM).
