Note: This list is an updated version of the invited speakers named in our proposal to the IAU. Due to cancellations the list has shrunk from 22 speakers to 18. The final list of speakers will, of course, be quite a bit longer. Indeed every talk (or other contribution) at an IAU Symposium requires an invitation through the SOC.

All proposed talk titles and abstracts received by the early registration deadline of Nov 15 were considered for oral presentations. Speakers were selected by having each of the SOC members vote on the list of proposed talks received by Nov 15. The resulting program is posted here. It comprises 60 talks and ~100 poster presentations.
