<Gordon I. Ogilvie> develops the fluid dynamics of astrophysical systems. His lecture notes connect conservation laws, <rotation> and magnetic fields with simplified models of stars and disks, while his accretion-disk teaching shows how boundary conditions constrain steady transport.<Lecture notes: Astrophysical fluid dynamics by Gordon I. Ogilvie>[Scope of the astrophysical-fluid equations]{ref}<Dynamics of Astrophysical Discs, Lecture 5: Boundary Conditions and Steady Accretion by Gordon I. Ogilvie>[Boundary conditions and steady accretion]{ref}
A local stress prescription alone does not fix an entire disk solution: the <mass> supply, <angular-momentum flux> and conditions at its boundaries must be specified as well.
