2021 Sagan Exoplanet Summer Virtual Workshop

Circumstellar Disks and Young Planets

Agenda

Speaker names are added as they are confirmed
All times are in the Pacific time zone


Notes on the Agenda:

Presentations:

The 2021 Sagan Summer Workshop will have a mix of pre-recorded and live presentations. We expect to post the pre-recorded talks by early July and shorter, live versions will be presented for many of these. In addition, the live talks will be recorded for eventual posting on the Sagan Summer Workshop YouTube channel.

Panel Discussions:

The panel discussions will give attendees a chance to ask questions in real time. Panel members will give a summary of their talks and then answer questions from the live audience, and any questions submitted ahead of time.

Virtual Poster Sessions and Poster Pops

The poster and Pop submission site will be open from June 21 to July 12. Please see this page for complete information.

Breakfast/Lunch with Speakers

These are small Zoom meetings with a single speaker and a limited attendance (~10) to give the attendees a chance to meet the speakers in a smaller, informal session. The sign-up for these will be available closer to the workshop.
