The Krome computational school (at its 6th edition) is designed to provide participants with an integrated foundation in the numerical, theoretical, and modeling approaches used to study star and planet formation. By covering the physical and chemical processes that operate from molecular clouds to mature planetary systems, the program emphasizes how modern computational techniques connect microphysical mechanisms with large-scale structure and evolution. Through lectures that span astrochemical modeling, radiation–thermochemical simulations, dust and gas dynamics, and advanced numerical methods, the school offers a coherent framework for understanding current challenges and frontiers in the field. This structure ensures that participants gain both conceptual grounding and practical experience with state-of-the-art tools, preparing them to contribute effectively to ongoing developments in computational astrophysics.
