Ivanovskistavro.ivanovski@iaps.inaf.itcircumstellar-dustDust grains have been collected on January-February and June-July 1994, during 51.8 hours of stratospheric (20 km of altitude) exposure, with large area (300 cm2) dust collectors mounted on a NASA ER-2 aircraft. The grains have been analyzed with a scanning electron microscope, equipped with a Si(Li) detector and PGT 4000T analyzer for X ray energy-dispersive spectrometry. A spectrum in the 0-10 KeV range for each particle has been obtained and its picture (not its data) published.http://vespa.ia2.inaf.it/tableinfo/ndcs.epn_coreCatalogResearchIsServedByINAF-OATs VESPA Data Service Hub TAP serviceNasa Dust CatalogueX-rayndcsDust grains have been collected on January-February and June-July 1994, during 51.8 hours of stratospheric (20 km of altitude) exposure, with large area (300 cm2) dust collectors mounted on a NASA ER-2 aircraft.
