Cool Stars 20.5 - virtually cool

March 2-4 2021, virtual meeting

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.

With the ongoing pandemic, the organizers of Cool Stars 21 consider it unlikely we will be able to meet in person in the summer of 2021. This would put a four year gap between our meetings for the first time. Therefore we have decided to hold a virtual conference to keep everyone in our field up to date. But don't worry, we still plan to meet in Toulouse in mid-2022.

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.
