Abstract: The main goal of the present work is to estimate the effects of plasma environment on the atomic parameters associated with the K-vacancy states in highly charged iron ions within the astrophysical context of accretion disks around black holes. In order to do this, multiconfiguration Dirac-Fock computations have been carried out by considering a time averaged Debye-H¨uckel potential for both the electron-nucleus and electron-electron interactions. In the present paper, a first sample of resu…
