The spectra of Hot Emission Stars and AGN present peculiar profiles that result from
dynamical processes such as accretion and/or ejection of matter from these objects. In this
paper we explain the idea of DACs and SACs phenomena, as a reason of spectral lines
peculiarity in Hot Emission Stars and AGN. We present the line function of a kinematical
model enabling us to study the physical parameters of the density regions in the plasma
surrounding of the studied objects, where DACs and SACs of a spectral line are created,
producing the observed peculiar profiles. Using this model, we study some AGN spectral
lines and we present an analysis of the physical parameters of the regions that these spectral
lines arise from. We also present some first general conclusions, derived from the proposed
model, including the relations among the physical parameters of the density regions of the
plasma surrounding the Oe stars, where DACs and SACs are created, producing the
observed peculiar profiles. Finally we present a first comparison of DACs and SACs
phenomena between Be and Oe stars. |
