University of Tsukuba, Center for Computational Sciences
This workshop aims to provide an opportunity to exchange views and share information about the current status of observations and theoretical research on a wide range of aspects concerning the formation of astronomical objects.
Moreover, it also serves as interim report by students in our research group who are working on dissertations.
This year, the meeting will be held over two days, November 4 and 5. In view of the coronavirus infection situation, we plan to have a hybrid format consisting of on-site participation in the CCS workshop room and online participation via Zoom.
Due to the ongoing risk of coronavirus infections, the workshop dinner will not take place.
You are welcome to upload your slides in advance. This will be helpful for everyone when following the talks online.
Registration is now closed.
