Parameters of normal and peculiar massive single and multiple stars

M.-F. Nieva and N. Przybilla

A precise characterization of stars through their fundamental parameters and chemical fingerprints is a basic and non-trivial step that complements the study of the stellar structure and evolution, allowing us to understand their nature in more detail. The large variety of massive stars present in nature prevents us to study them in a unique way and challenges standard spectral modeling and analyses. We summarize investigations from the past 12 years on the analysis of different kind of massive stars, from the simplest single objects to multiple systems. The scope of this review is to provide the broader community with tools (biased towards our experience) to judge results from spectroscopic studies to complement analyses of stellar variability using photometric observations.
