Accretion Disks Several members of VITA work on accretion disks and related phenomena.
Balbus and Hawley are investigating the magnetohydrodynamics of accretion disks. They have been carrying out computer simulations of magnetohydrodynamical turbulence in disks and the angular momentum transport that results. Zhi-Yun Li's research concerns protostellar disks and magnetohydrodynamic winds from disk systems. The initial velocity instabilities disappear after a number of orbits. The second pair of images shows the initial and final states of a shearing box using magnetohydrodynamic code.
