描述This book introduces the theory of stellar atmospheres. Almost everything we know about stars is by analysis of the radiation coming from their atmospheres. Several aspects of astrophysics require accurate atmospheric parameters and abundances. Spectroscopy is one of the most powerful tools at an astronomer’s disposal, allowing the determination of the fundamental parameters of stars: surface temperature, gravity, chemical composition, magnetic field, rotation and turbulence. These can be supplemented by distance measurements or pulsation parameters providing information about stellar interior and stellar evolution, otherwise unavailable. .The volume is based on lectures presented at the Wroc?aw‘s Spectroscopic School aimed at training young researchers in performing quantitative spectral analysis of low-, mid-, and high-resolution spectra of B, A, and F-type stars.

Problems with Atomic and Molecular Data: Including All the Lines,n 25?years ago. I am recomputing the existing line lists including many more configurations and energy levels and producing many more lines. I am collecting more recent data from the literature, and I am extending the calculation to heavier elements and higher stages of ionization. I will produce mo

Effective Temperature Determination,ussion of the methods for determining effective temperature using stellar spectra is presented. The use of Balmer line profiles is explored and the role of spectral line depth ratios outlined. Equivalent width measurements are a powerful tool for determining effective temperature, via the excitation
