The Teeminar (= Tee Seminar) is the weekly meeting connected to the stellar dynamics group for discussion of a selected topic. In times before the Corona crisis Teeminar was held in Heidelberg and Beijing. The ONLINE Teeminar takes place currently at Tuesday, 13:00 - 14:30 (European Time CET=UTC+1), the time may change occasionally due to geographic constraints of our speakers. In winter CET=UTC+1, in summer CEST=UTC+2, please check your local time zones). The Teeminar is intended to be a discussion of ongoing work/problems. Note that complete presentations are neither required nor expected. However, guests may make more formal presentations if they prefer. Discussing new plots and questions from current work and the use of laptop and whiteboard is encouraged! For more information please contact This email address is being protected from spambots.
