*First Announcement*

Dear colleagues,

We are pleased to announce the International Astronomical Union Symposium 398 
“Compact Objects and Binaries in Dense Stellar Systems” which will take place 
June 16-20, 2025, in Seoul National University, Seoul, Korea. This meeting will 
also be held as MODEST-25, annual workshop series for Modeling and Observing 
Dense Stellar Systems.

This symposium is intended to discuss the astrophysical origin of gravitational 
waves and to establish connections between theoretical and observational data 
concerning dynamics, populations, binaries, multiples, compact objects 
(including binaries containing them) in dense star clusters. Star clusters serve 
as dynamical factories for all these intriguing objects, and these topics are 
inherently interconnected. For instance, cluster dynamics and the evolution of 
single and binary stars are closely intertwined, leading to different scenarios 
compared to those in the galactic field. We believe that the year 2025 is an 
appropriate time to delve into the topic of star clusters and the roles of 
compact objects. This timing aligns with the release of significant results from 
the fourth observing run of LIGO/Virgo/KAGRA, which should provide crucial new 
constraints on the formation of gravitational wave sources. Additionally, 
numerous new discoveries of globular cluster pulsars are expected from large 
radio facilities such as MeerKAT, ASKving DeAP, FAST, and others. New computer 
codes for dynamical simulations of dense star clusters are also emerging, and 
this symposium offers an excellent opportunity to discuss the latest results 
based on these codes.
