Abstract: In the context of black-hole accretion disks, we estimate the effects of the plasma environment on the atomic parameters associated with K-vacancy states in He- and Li-like oxygen ions. Multiconfiguration Dirac–Fock and Breit–Pauli computations have been carried out assuming a time-averaged Debye–Hückel potential for both the electron–nucleus and electron–electron interactions. Plasma effects on the ionization and excitation thresholds, transition wavelengths, and radiative emission rates are reported for O VI and O VII.
