Meetings‎ > ‎2016 Seggau‎ > ‎


The science sessions of the workshop will take place between Tuesday morning and Wednesday evening (ending around 4:30pm to allow people to catch flights from Graz around 7pm). There will be a wine tasting on Monday evening to welcome us to the venue.

Scientific agenda



This meeting is designed to allow collaboration and discussion on how best to combine results from different teams and different telescopes, and how to provide cross over between Rosetta instrument results and ground-based observations. As such there is plenty of time scheduled for discussion on various topics, rather than a fixed format of talks. Introductory talks on Rosetta results and outlining observations will be followed by sessions on specific themes, which will contain short talks on modelling & more detailed results.
