報告摘要：Computational simulations are essential tools in astrophysics today and many codes are publicly available. Athena++ is a magnetohydrodynamics simulation code we develop in international collaboration led by Institute for Advanced Study / Princeton University. This code supports adaptive mesh refinement and various physical processes for astrophysical applications, and adopts new concepts to improve the performance and parallel scalability. There is nothing like "One code to solve them all", but we aim to make Athena++ a versatile, high-performance, easy-to-use, one of the best codes in the field. In this presentation, I will explain the design and strategy of Athena++, some scientific results (mainly about star formation and protoplanetary disks) and future plans.
主講人簡介：Kengo Tomida is an associate professor at Astronomical Institute, Tohoku University. He received his PhD from the Graduate University for Advanced Studies in 2012 and worked as a postdoc in Department of Astrophysical Sciences,Princeton University. He moved to Osaka University in 2015 as an assistant professor, and he started his current position in 2020. His research interests include computational astrophysics and formation of stars, protoplanetary disks and planets. He is one of the core developers of the public astrophysical MHD simulation code Athena++.
