cds-question@unistra.frsupernova-remnantsproper-motionsx-ray-sourcesWe present high-resolution X-ray proper-motion measurements of Cassiopeia A using Chandra X-Ray Observatory observations from 2000 and 2002. We separate the emission into four spectrally distinct classes: Si-dominated, Fe-dominated, low-energy-enhanced, and continuum-dominated. These classes also represent distinct spatial and kinematic components.2004ApJ...613..343Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/613/343CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/441/307 : Proper motions and brightness of Cas A (Anderson+ 1995)J/ApJ/456/234 : Cas A radio knots spectral indices (Anderson+ 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/613/343https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/613/343http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/613/343https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/613/343https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/613/343http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/613/343GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapX-raydefaultJ/ApJ/613/343/table1Knot and filament proper motionsrecnoRecord number assigned by the VizieR team.
