cds-question@unistra.fratomic-physicsIn the context of black-hole accretion disks, we have computed plasma environment effects on the atomic parameters used to model the decay of K-vacancy states in moderately charged iron ions, namely FeIX-FeXVI. We use the fully relativistic multiconfiguration Dirac-Fock (MCDF) method approximating the plasma electron-nucleus and electron-electron screenings with a time-averaged Debye-Huckel potential. Modified ionization potentials, K thresholds, wavelengths, radiative emission rates and Auger widths are reported for astrophysical plasmas characterized by electron temperatures and densities respectively in the ranges 10^5^-10^7^K and 10^18^-10^22^cm^-3^. This study confirms that the high-resolution X-ray spectrometers onboard the future XRISM and ATHENA space missions could detect the lowering of the K edges of these ions due to the extreme plasma conditions occurring in accretion disks around compact objects.2020A&A...635A..70Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/635/A70CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/635/A70https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/635/A70http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/635/A70https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/635/A70https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/635/A70http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/635/A70GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/635/A70/table5Wavelengths and Transition probabilitiesrecnoRecord number assigned by the VizieR team.
