Cool Stars 20.5 - virtually cool on March 2-4 2021
in Memory of John Stauffer
The "Cambridge Workshops of Cool Stars, Stellar Systems and the Sun" are held biennially and have evolved to be the premier conference series for cool star research.
Posters
We will host a virtual Social Hour (Tuesday), and a virtual Poster Session (Wednesday) during the Topical Interest Room times (4-5PM EST). These events will be hosted using Gather.Town, a virtual environment that runs in your web browser with a 90’s video game feel. The link to join will be circulated to registered attendees. Gather.Town allows attendees to walk around, play games, and video chat with those nearby. We’ve found this platform is fun, easy to use, and helps capture some of the magic of “bumping into colleagues” that we all miss!
We currently have capacity for 48 posters at Wednesday’s session. (More can be added if demand is high) Poster slots are on a first-come basis. To request a poster slot email James Davenport with a single JPEG version of your poster (3MB file size limit). You will be assigned a poster room and poster #. During the Poster Session (Wednesday) you should stand by or near your poster just like you would at a normal conference.
