Motivation
Here is a list of some interesting open problems in astrophysical dynamics. Most have been chosen by James Binney, but suggestions for new problems are also welcome.
Workshop
These problems were the starting point for discussion at a workshop that took place at Magdalen College, Oxford, from 8 to 14 August 2010. Attendance at the workshop was open to anyone who worked on at least one of the problems in advance and was willing to present his/her attempts. The number of participants was limited to about 25.
