POSYDON SCHOOL 
2025

23-26 September, 

NSF-Simons SkAI Institute
John Hancock Center, Chicago, IL

The first POSYDON school

Learn how to use POSYDON, a state-of-the-art binary population synthesis code now in its second version, and discover its unique capabilities. This four day workshop aims to familiarize participants with the code so they can effectively incorporate it into their own research.


Through a series of hands-on labs, we will explore exciting astrophysical scenarios such as mass-transfer stability, supernovae, binary black-hole populations, and more, showcasing how POSYDON can advance your research goals. By the end of the school, you will be ready to apply your newfound expertise, share your knowledge with colleagues, and push single and binary stellar population research to new frontiers.

Registration Open

Everyone interested should apply and we will do our best to accomodate as many as possible, although space is limited. We will send acceptance letters at the end of May to let you know if we can accomodate you (please email posydon.school@gmail.com with questions or concerns). Before applying, please have in mind:

  • Breakfast and lunch will be provided daily.
  • We request that all participants plan to attend the entire week of the school (Sept. 23 - 26th).
  • Applicants are not expected to know how to use POSYDON, but are expected to have it installed prior to arriving (installation instructions here).
  • We recommend that participants read the instrument papers for POSYDON v1 and POSYDON v2 to familiarize yourself with the code infrastructure.
  • Familiarity with Python and command line usage is expected.
  • Undergraduate, master's, and PhD students, please obtain the permission of your advisor before applying. We will contact your advisor to confirm that you have finanicial support for accomodation and travel, and that you meet the availability and preparedness requirements. A small number of scholarships may be available to support students lacking financial support, but we can not guarantee this.
