Welcome to the Exocoffee webpage! Exocoffee is a journal club of the APEx Department at MPIA where we discuss exoplanet papers. If you've read or written an interesting paper that you want to put on the agenda for Exocoffee, please send it to the organizers. Don't be shy! It can be anything exoplanet related, and we try to keep an informal environment - just showing off some of your figures is totally fine.
Exocoffee typically takes place every Tuesday, at 2 pm CET in MPIA's seminar room in a hybrid mode. Subscribers of the Exocoffee mailing list will get the link to the meeting on the day of Exocoffee.
