Schematic comparison of FASTWIND v10 and v11 (in red): specific methods and data regarding the treatment of explicit and background elements.

Background elements

Explicit elements Selected Non-selected
(e.g., H, He; H, He, N; (typically: C, N, O, Mg, Ne, Si, P, S, Ar, (remaining elements until
H, He, C, N, O, …) Fe, Ni, minus explicit elements) Zn, without Li, Be, B, Sc)
Atomic data (v10 ) User supplied (a) Fixed, from WM-BASIC (b) database

NLTE (v10 ) Exact Exact Approximate (c)

v10: radiative transfer CMF Strong lines: CMF; weaker lines: Sobolev, irradiated by
for individual lines wind: Sobolev; photosphere: static pseudo-continuum


v10: mean intensity for From pseudo-continuum with bound-free and free–free Expressed in terms
photoionization rates opacities/emissivities from all elements, and combined (c) of Trad from
and other quantities line opacities/source-functions from background elements pseudo-continuum

Notes. The default values for λmin and λmax are 200 and 10 000 Å, respectively. For further details, see text. (a)DETAIL (Butler & Giddings 1985)-like input format, (b)Pauldrach et al. (2001), (c)see Puls et al. (2005), (d) see Appendix C.1.
