Non-LTE Line Formation in the Near-IR: Hot Stars

  • R. Monier, B. Smalley, G. Wahlgren, Ph. Stee and N. Przybilla (a1)...

Abstract

Line-formation calculations in the Rayleigh-Jeans tail of the spectral energy distribution are complicated by an amplification of non-LTE effects. For hot stars this can make quantitative modelling of spectral lines in the near-IR challenging. An introduction to the modelling problems is given and several examples in the context of near-IR line formation for hydrogen and helium are discussed.
