A star in a binary may interact with its companion and this complicates significantly its structure and evolution. During several decades in the past many astronomers hoped that the number of binaries is small. This is sometimes reflected in theoretical studies dealing with large populations of stars where it is ASSUMED (without any justification) that binaries do not alter the results. The number of confirmed binaries increases as observations improve and we there fore thought that the time was right to organize a meeting where the main topic would be the effect of binaries on stellar...

This book reviews recent observations of non-evolved and evolved binary populations in clusters and the field with special emphasis on statistical biases, incompleteness, and distribution functions. It considers different binary types and presents and discusses recent results in the field.

This book presents a complete overview of what we know, and would like to know, about the evolution and structure of massive stars. The spectra of early-type stars are produced by elaborate model atmospheres enveloping the internal structure.

The evolution of galaxies is governed mainly by the evolution of massive stars whereas the evolution of a massive star depends primarily on its mass, chemical composition and on whether or not the star is a Single object or a binary component. To study the evolution of galaxies, it is therefore essential to know how stellar masses are distributed at birth, how many stars are formed in binaries, and what the mass ratio and orbital period distribution of binaries look like. Massive stars are intrinsically the brightest stars, so that it may be possible to discover their properties in distant...

Massive stars occupy an exceptional place in general astrophysics. They trigger many if not all of the important processes in galactic evolution whereas due to their intrinsic brightness, they offer the (only until now) possibility to study the stellar content and stellar behaviour in distant galaxies. The last, say, 25 years, massive stars have been the subject of numerous meetings discussing the influence of massive stars on population synthesis, the number distribution of different types of massive stars, the LBV phenomenon, WR stars, X-ray binaries, stellar winds in massive stars,...

Der praxisorientierte Leitfaden dokumentiert die Herausforderungen und Risiken der Geschaftsprozesse anhand realer Fall- und Rechenbeispielen und zeigt verschiedene Gestaltungsmodelle mit erweiterten Vermarktungsmoglichkeiten auf. Der Schwerpunkt des Buches liegt in der Analyse der Spannungsfelder, die sich beim theoretischen und praktischen Aufbau einer B2B-Losung ergeben. Es stellt die optimale Umsetzung der Materialbewirtschaftung (Supply Chain Management) mit Fulfillment und der erforderlichen kontinuierlichen Leistungsmessung und -bewertung heraus."
