The conference Binary and Multiple Stars in the Era of Big Sky Surveys will be followed by the Pro-Am conference 56th Conference On Variable Star Research Pro-Am Meeting On Variable Stars organized by Variable Stars and Exoplanet Section of Czech Astronomical Society.

This section is very active, and the results and products made by the members are widely used by the whole community working on variable stars or exoplanets research. Let me mention e.g. O-C gate, ETD (Exoplanet Transit Database), OEJV (Open European Journal on Variable Stars), papers about (multiple) eclipsing systems (e.g. 2023A&A...675A.113Z, 2022A&A...667A..53P, 2020A&A...643A.130Z).

These are excellent examples of collaboration between amateur and professional researchers.
