Scope 
As the number of confirmed exoplanets surpasses 6,000, it is becoming increasingly clear that planetary systems display an extraordinary diversity, often starkly different from our own Solar System. We are now entering a transformative era in which the full breadth of planetary architectures and atmospheric composition is gradually coming into view. 
The JWST has opened a new window into exoplanetary atmospheres, providing unprecedented insights into their chemical and physical properties. Looking ahead, upcoming missions and facilities such as Ariel, TMT, ELT, and HWO will further deepen our understanding of planetary diversity.
Exoplanetary science is becoming not only a distinct branch of astronomy but also of Earth-Planetary Science. To advance this field, we must engage in comprehensive discussions from a variety of scientific backgrounds, such as stellar physics, disk evolution, planetary formation, climate, and chemistry. 
This session aims to bring together researchers from diverse scientific backgrounds to share recent results, highlight the status of ongoing and upcoming exoplanet missions, and promote cross-disciplinary discussions. We welcome contributions from all related fields to deepen our collective understanding of exoplanetary systems.
