Dear participants! We would like to welcome all of you to the conference ”Why Galaxies Care About AGB Stars - Their importance as actors and probes”. This conference aims to build a bridge between AGB research and its application to the modelling of stellar pop- ulations and the chemical evolution of galaxies. Current developments and chal- lenges on both sides will be discussed to reach an understanding of possibilities, limitations, and needs in both areas, and hence to improve our knowledge about the role of AGB stars in the context of galaxies. For more than 15 years AGB stars are now one of the main research topics at the Department of Astronomy at the University of Vienna. The questions addressed include atmospheric structure, variability, nucleosynthesis and mass loss. Currently interests focus on aspects of abundance determination, on the mid- and far-infrared range (participation in the HERSCHEL satellite) and on interferometry as a tool to study the dynamic atmospheres of long period variables. 250 years ago the first observatory of the University of Vienna was opened. During the conference dinner you will have the possibility to visit the second Vienna Univer- sity Observatory built between 1874 and 1879. While being a place full of history it is today a vivid centre for modern astrophysical research. This conference is hosted by the Austrian Society for Astronomy and Astrophysics and the Department of Astronomy at the University of Vienna. The meeting is co- sponsored by the IAU Working Group on Abundances in Red Giants. We thank the Robert Wing Support Fund, the Austrian Federal Ministery for Education, Science and Culture, the University of Vienna and several sponsors. We hope you all have an excellent and stimulating conference, and that you enjoy Austria and Vienna.

A LOC member will assist you during the coffee breaks and before the morning and the afternoon sessions. If you wish to use an overhead projector please let us know in advance. Name badges: Admission of participants to all sessions is by the conference name badge only. Participants are requested to wear their name badge at all times. Posters: Posters are on display in the foyer of the lecture hall during the whole meeting. Authors are asked to be available at their posters for discussion during the breaks. Each poster board is numbered, numbers are given in this abstract book. LOC members will be around to help you find the location of your poster. Please mount your poster before 10:30 on Monday morning and remove it until 16:00 on Friday. 7 SOCIAL PROGRAM WALKING TOUR ”VIENNA AT FIRST GLANCE” This orientational tour gives you a nice overwiew over the city. Beside the main sight in the city center like the Imperial Palace and St. Stephan’s Cathedral we also dive into more off-the-beaten-track parts of the city with its small streets and hidden courtyards.
