Modelling the spectra of early-type stars using the ADS approach
Andreas Irrgang, Simon Kreuzer, Norbert Przybilla, Keith Butler, Ulrich Heber


To model spectra of early-type stars, the so-called ADS (or hybrid) approach can be employed. It consists of three steps, i.e., codes: ATLAS12, DETAIL, and SURFACE. The underlying idea is that non-local thermodynamic equilibrium (non-LTE) effects are important for the details of radiative transfer but negligible for the atmospheric structure. We will discuss the pros and cons of this approach as well as present recent improvements.
