*Please note: While talks will be listed in the IAUC198 abstract booklet in the usual way (title+abstract), participants with poster presentations will have the opportunity to submit an A4 version of their posters to the LOC before the meeting. These A4 versions will then be printed in full in the abstract booklet to increase the visibility of the scientific results that are presented on posters during the conference.
