NLTE Analysis of Spectra: OBA Stars,ation. Differences between LTE and NLTE atmosphere modelling are evaluated. The ways of model atom construction are discussed. Finally, modelling of expanding atmospheres of hot stars with winds is briefly reviewed.

NLTE Radiative Transfer in Cool Stars,adiative transfer models are often computed using the assumption of local thermodynamic equilibrium (LTE). Its validity is often questionable and needs to be supported by detailed studies, which build upon the consistent framework of NLTE. In this review, we outline the theory of NLTE. The processes

Analysis of Stellar Spectra with 3-D and NLTE Models,s only as good as the theoretical models which are used for the interpretation of their observed spectra, photometric magnitudes, and spectral energy distributions. I describe recent advances in the field of stellar atmosphere modelling for late-type stars. Various aspects of radiation transport wit

Spectroscopic Analysis of Cool Giants and Supergiants,to enormous distances allowing us to study the properties of their host galaxies, such as dynamics and chemical abundances. This review lecture addresses various problems related to observations and modelling spectra of red giants and supergiants.

Effective Temperature Determination, potential method. This is explored in detail including the sensitivity to surface gravity and metal abundance. The discussion leads to the use of spectrum synthesis fitting to determine effective temperature.
