Iron abundances from optical Fe III absorption lines in B-type stellar spectra [PDF]

, 2007
The role of optical Fe III absorption lines in B-type stars as iron abundance diagnostics is considered. To date, ultraviolet Fe lines have been widely used in B-type stars, although line blending can severely hinder their diagnostic power. Using optical

Vulnerability of LTE to Hostile Interference

, 2014
LTE is well on its way to becoming the primary cellular standard, due to its performance and low cost. Over the next decade we will become dependent on LTE, which is why we must ensure it is secure and available when we need it.

Non-LTE calculations for neutral Na in late-type stars using improved atomic data

, 2011
Neutral sodium is a minority species in the atmospheres of late-type stars, and line formation in local thermodynamic equilibrium (LTE) is often a poor assumption, in particular for strong lines.
