Stellar winds from hot stars are not homogeneous, spherically symmetric or stationary. There are multiple lines of evidence for ''wind clumping'', coming from
No consistent understanding exists yet about the physics, geometry and
parameters of the wind clumping. The urgent interest in this problem is
boosted by its far-reaching implications. Most important, all techniques
to derive empirical mass-loss rates are more or less corrupted by wind
clumping. Consequently, mass-loss rates are extremely uncertain. Within
this range of uncertainty, completely different scenarios for the
evolution of massive stars are obtained. Settling these questions for
Galactic OB, LBV and Wolf-Rayet stars is prerequisite to understanding
stellar clusters and galaxies, or predicting the properties of
first-generation stars.
Wind clumping is under investigation from various observational and
theoretical approaches. When combining all different pieces of
information, it should be possible to obtain a picture that unifies the
empirical manifestations with a theoretical understanding of
inhomogeneous stellar winds.
The intention of the workshop is to bring together all experts in the
field, in order to develop such a consistent picture and understanding
of clumped stellar winds during one week of extensive exchange and
discussion.

The meeting will be held in the Kongresshotel Potsdam
(www.kongresshotel-potsdam.de). This hotel is located in the outskirts of
Potsdam, at a lakeside but only a few tram stations from the city center.
Potsdam neighbors the German capital Berlin, and is easily reached from the
international Airports Berlin-Tegel (TXL) and Berlin-Schönefeld (SFX).
The hotel offers a package, comprising

The workshop will concentrate on oral presentations and extended discussions. Only very few posters can be accepted.
The conference proceedings will be published mainly electronically.
The official publisher is the Universitaetsverlag Potsdam. ADS will give
links to the articles, and after three years ADS will also archive the
files.
A limited number of paper copies will be printed (paperback,
simple binding) and provided for the participants.
The capacity of the workshop is limited to 50 participants.
Preregistration is open from now onwards. Please send an email to: , stating your
The registration fee will be 220 Euro (270 Euro for late registration after 1st of March, 2007). It includes an excursion and the conference dinner. Accompanying persons may register for 100 Euro to participate in the social events.
