Computational Astrophysics Research Group

The computational astrophysics research group at IASTU primarily focuses on two areas: protoplanetary disks and planet formation, and plasma astrophysics, mostly by means of numerical simulations using various tools (primarily Athena++ MHD code). On the former, we study many aspects of gas dynamics in protoplanetary disks, as well as implications to observations and planet formation theory. On the latter, we study accretion disks, particle acceleration, cosmic-ray feedback, and dilute plasmas. Besides utilizing existing infrastructure including those we have built in the past, some group members also work on additional code (and algorithm) developments to build up more tools, opening up new windows and research opportunities.
