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.
Wondering where everyone is coming from? Who connects to our zoom? Below is some geographical insight comparing Cool Stars 20 (in Boston, MA, USA) with Cool Stars 20.5 which allows everyone to register for free, reducing access for students, post-Docs, and researchers who cannot fly half-way around the world (e.g. because of limited funding, child care or other commitments at home, or because they want to reduce CO2 emission from travel).
In both cases, this is based on registration data. Matching is done through automated query of bing maps and may not be correct in all cases (e.g. two participants listed their affiliation as "astronom", which gets mapped to an address in Denmark). Participants who did not provide an affiliation are located based on their email address (e.g. an address ending on ".de" will place a marker somewhere in Germany).
For CS21, we do not charge a registration fee and we know some participants registered more than once. We have done a reasonable effort to remove those cases by hand, but that is not possible for registrations that are annomymous (no name, no affiliation), thus the number of registrations is too high, by about 10% or so.
