Aims.In the context of black-hole accretion disks, the main goal of the present study is to estimate the plasma environment effects on the atomic structure and radiative parameters associated with the K-vacancy states in ions of the oxygen isonuclear sequence.
Methods. We used a time-averaged Debye-Huckel potential for both the electron-nucleus and the electron-electron interactions implemented in the fully relativistic multiconfiguration Dirac-Fock (MCDF) method.
Results. Modified ionization potentials, K thresholds, Auger widths, and radiative transition wavelengths and rates are reported for OI-OVII in plasma environments with electron temperature and density ranges 10⁵-10⁷K and 10¹⁸-10²²cm^–3.
