Cyclical Variability in Stellar Winds: Proceedings of the ESO Workshop Held at Garching, Germany, 14 – 17 October 1997 (ESO Astrophysics Symposia)

It is well known that stellar winds are variable, and the fluctuations are often cyclical in nature. This property seems to be shared by the winds of cool and hot stars, even though their outflows are driven by fundamentally different physical mechanisms. Since very similar models have been proposed to explain the cyclical wind variations observed in a wide variety of stars, the time was ripe for astrophysicists from many different sub-disciplines to present the state of the art in a concise form. The proceedings will provide a useful, up-to-date overview of the observations, interpretation, and modelling of the time-dependent mass outflows from all sorts of stars.

It is well known that stellar winds are variable. Recent investigations show that the observed fluctuations are often cyclical in nature. This property seems to be shared by the winds of cool and hot stars, even though the physical mechanisms driving these winds are fundamentally different. The time was ripe for astrophysicists studying different types of stars, but applying very similar models, to present the state of the art in a concise form. The proceedings will provide a useful, up-to-date overview of the observations, interpretation, and modelling of the time-dependent mass outflows from a wide variety of stars, including young, pre-main-sequence objects, solar-type stars, red supergiants, and hot, massive stars.
